spack.modules.commmon: pass spec to SetupContext

Currently module globals aren't set before running
`setup_[dependent_]run_environment` to compute environment modifications
for module files. This commit fixes that.

-`v0.21.0` is a major feature release.

-## Features in this release
-
-1. **Better error messages with condition chaining**
-
-   In v0.18, we added better error messages that could tell you what problem happened,
-   but they couldn't tell you *why* it happened. `0.21` adds *condition chaining* to the
-   solver, and Spack can now trace back through the conditions that led to an error and
-   build a tree of causes potential causes and where they came from. For example:
-
-   ```console
-   $ spack solve hdf5 ^cmake@3.0.1
-   ==> Error: concretization failed for the following reasons:
-
-      1. Cannot satisfy 'cmake@3.0.1'
-      2. Cannot satisfy 'cmake@3.0.1'
-           required because hdf5 ^cmake@3.0.1 requested from CLI
-      3. Cannot satisfy 'cmake@3.18:' and 'cmake@3.0.1
-           required because hdf5 ^cmake@3.0.1 requested from CLI
-           required because hdf5 depends on cmake@3.18: when @1.13:
-             required because hdf5 ^cmake@3.0.1 requested from CLI
-      4. Cannot satisfy 'cmake@3.12:' and 'cmake@3.0.1
-           required because hdf5 depends on cmake@3.12:
-             required because hdf5 ^cmake@3.0.1 requested from CLI

-
-2. **OCI build caches**
-
-   You can now use an arbitrary [OCI](https://opencontainers.org) registry as a build
-   cache:
-
-   ```console
-   $ spack mirror add my_registry oci://user/image # Dockerhub
-   $ spack mirror add my_registry oci://ghcr.io/haampie/spack-test # GHCR
-   $ spack mirror set --push --oci-username ... --oci-password ... my_registry  # set login creds
-   $ spack buildcache push my_registry [specs...]
-   ```
-
-   And you can optionally add a base image to get *runnable* images:
-
-   ```console
-   $ spack buildcache push --base-image ubuntu:23.04 my_registry python
-   Pushed ... as [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack
-
-   $ docker run --rm -it [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack
-   ```
-
-   This creates a container image from the Spack installations on the host system,
-   without the need to run `spack install` from a `Dockerfile` or `sif` file. It also
-   addresses the inconvenience of losing binaries of dependencies when `RUN spack
-   install` fails inside `docker build`.
-
-   Further, the container image layers and build cache tarballs are the same files. This
-   means that `spack install` and `docker pull` use the exact same underlying binaries.
-   If you previously used `spack install` inside of `docker build`, this feature helps
-   you save storage by a factor two.
-
-   More details in #38358.
-
-3. **Multiple versions of build dependencies**
-
-   Increasingly, complex package builds require multiple versions of some build
-   dependencies. For example, Python packages frequently require very specific versions
-   of `setuptools`, `cython`, and sometimes different physics packages require different
-   versions of Python to build. The concretizer enforced that every solve was *unified*,
-   i.e., that there only be one version of every package. The concretizer now supports
-   "duplicate" nodes for *build dependencies*, but enforces unification through
-   transitive link and run dependencies. This will allow it to better resolve complex
-   dependency graphs in ecosystems like Python, and it also gets us very close to
-   modeling compilers as proper dependencies.
-
-   This change required a major overhaul of the concretizer, as well as a number of
-   performance optimizations. See #38447, #39621.
-
-4. **Cherry-picking virtual dependencies**
-
-   You can now select only a subset of virtual dependencies from a spec that may provide
-   more. For example, if you want `mpich` to be your `mpi` provider, you can be explicit
-   by writing:
-
-   ```
-   hdf5 ^[virtuals=mpi] mpich
-   ```
-
-   Or, if you want to use, e.g., `intel-parallel-studio` for `blas` along with an external
-   `lapack` like `openblas`, you could write:
-
-   ```
-   strumpack ^[virtuals=mpi] intel-parallel-studio+mkl ^[virtuals=lapack] openblas
-   ```
-
-   The `virtuals=mpi` is an edge attribute, and dependency edges in Spack graphs now
-   track which virtuals they satisfied. More details in #17229 and #35322.
-
-   Note for packaging: in Spack 0.21 `spec.satisfies("^virtual")` is true if and only if
-   the package specifies `depends_on("virtual")`. This is different from Spack 0.20,
-   where depending on a provider implied depending on the virtual provided. See #41002
-   for an example where `^mkl` was being used to test for several `mkl` providers in a
-   package that did not depend on `mkl`.
-
-5. **License directive**
-
-   Spack packages can now have license metadata, with the new `license()` directive:
-
-   ```python
-       license("Apache-2.0")
-   ```
-
-   Licenses use [SPDX identifiers](https://spdx.org/licenses), and you can use SPDX
-   expressions to combine them:
-
-   ```python
-       license("Apache-2.0 OR MIT")
-   ```
-
-   Like other directives in Spack, it's conditional, so you can handle complex cases like
-   Spack itself:
-
-   ```python
-      license("LGPL-2.1", when="@:0.11")
-      license("Apache-2.0 OR MIT", when="@0.12:")
-   ```
-
-   More details in #39346, #40598.
-
-6. **`spack deconcretize` command**
-
-   We are getting close to having a `spack update` command for environments, but we're
-   not quite there yet. This is the next best thing. `spack deconcretize` gives you
-   control over what you want to update in an already concrete environment. If you have
-   an environment built with, say, `meson`, and you want to update your `meson` version,
-   you can run:
-
-   ```console
-   spack deconcretize meson
-   ```
-
-   and have everything that depends on `meson` rebuilt the next time you run `spack
-   concretize`. In a future Spack version, we'll handle all of this in a single command,
-   but for now you can use this to drop bits of your lockfile and resolve your
-   dependencies again. More in #38803.
-
-7. **UI Improvements**
-
-   The venerable `spack info` command was looking shabby compared to the rest of Spack's
-   UI, so we reworked it to have a bit more flair. `spack info` now makes much better
-   use of terminal space and shows variants, their values, and their descriptions much
-   more clearly. Conditional variants are grouped separately so you can more easily
-   understand how packages are structured. More in #40998.
-
-   `spack checksum` now allows you to filter versions from your editor, or by version
-   range. It also notifies you about potential download URL changes. See #40403.
-
-8. **Environments can include definitions**
-
-   Spack did not previously support using `include:` with The
-   [definitions](https://spack.readthedocs.io/en/latest/environments.html#spec-list-references)
-   section of an environment, but now it does. You can use this to curate lists of specs
-   and more easily reuse them across environments. See #33960.
-
-9. **Aliases**
-
-   You can now add aliases to Spack commands in `config.yaml`, e.g. this might enshrine
-   your favorite args to `spack find` as `spack f`:
-
-   ```yaml
-   config:
-     aliases:
-       f: find -lv
-   ```
-
-   See #17229.
-
-10. **Improved autoloading of modules**
-
-    Spack 0.20 was the first release to enable autoloading of direct dependencies in
-    module files.
-
-    The downside of this was that `module avail` and `module load` tab completion would
-    show users too many modules to choose from, and many users disabled generating
-    modules for dependencies through `exclude_implicits: true`. Further, it was
-    necessary to keep hashes in module names to avoid file name clashes.
-
-    In this release, you can start using `hide_implicits: true` instead, which exposes
-    only explicitly installed packages to the user, while still autoloading
-    dependencies. On top of that, you can safely use `hash_length: 0`, as this config
-    now only applies to the modules exposed to the user -- you don't have to worry about
-    file name clashes for hidden dependencies.
-
-   Note: for `tcl` this feature requires Modules 4.7 or higher
-
-11. **Updated container labeling**
-
-    Nightly Docker images from the `develop` branch will now be tagged as `:develop` and
-    `:nightly`. The `:latest` tag is no longer associated with `:develop`, but with the
-    latest stable release. Releases will be tagged with `:{major}`, `:{major}.{minor}`
-    and `:{major}.{minor}.{patch}`. `ubuntu:18.04` has also been removed from the list of
-    generated Docker images, as it is no longer supported. See #40593.
-
-## Other new commands and directives

-Build cache signing
--------------------
-
-By default, Spack will add a cryptographic signature to each package pushed to
-a build cache, and verifies the signature when installing from a build cache.
-
-Keys for signing can be managed with the :ref:`spack gpg <cmd-spack-gpg>` command,
-as well as ``spack buildcache keys`` as mentioned above.
-
-You can disable signing when pushing with ``spack buildcache push --unsigned``,
-and disable verification when installing from any build cache with
-``spack install --no-check-signature``.
-
-Alternatively, signing and verification can be enabled or disabled on a per build cache
-basis:
-
-.. code-block:: console
-
-    $ spack mirror add --signed <name> <url>  # enable signing and verification
-    $ spack mirror add --unsigned <name> <url>  # disable signing and verification
-
-    $ spack mirror set --signed <name>  # enable signing and verification for an existing mirror
-    $ spack mirror set --unsigned <name>  # disable signing and verification for an existing mirror
-
-Or you can directly edit the ``mirrors.yaml`` configuration file:
-
-.. code-block:: yaml
-
-    mirrors:
-      <name>:
-        url: <url>
-        signed: false # disable signing and verification
-
-See also :ref:`mirrors`.

-Relocation
-----------
-
-When using buildcaches across different machines, it is likely that the install
-root will be different from the one used to build the binaries.
-
-To address this issue, Spack automatically relocates all paths encoded in binaries
-and scripts to their new location upon install.
-
-Note that there are some cases where this is not possible: if binaries are built in
-a relatively short path, and then installed to a longer path, there may not be enough
-space in the binary to encode the new path. In this case, Spack will fail to install
-the package from the build cache, and a source build is required.
-
-To reduce the likelihood of this happening, it is highly recommended to add padding to
-the install root during the build, as specified in the :ref:`config <config-yaml>`

-Spack build cache for GitHub Actions
+Using a buildcache in GitHub Actions
 ------------------------------------
 
-To significantly speed up Spack in GitHub Actions, binaries can be cached in
-GitHub Packages. This service is an OCI registry that can be linked to a GitHub
-repository.
+GitHub Actions is a popular CI/CD platform for building and testing software,
+but each CI job has limited resources, making from source builds too slow for
+many applications. Spack build caches can be used to share binaries between CI
+runs, speeding up CI significantly.
 
-Spack offers a public build cache for GitHub Actions with a set of common packages,
-which lets you get started quickly. See the following resources for more information:
+A typical workflow is to include a ``spack.yaml`` environment in your repository
+that specifies the packages to install:
 
-* `spack/setup-spack <https://github.com/spack/setup-spack>`_ for setting up Spack in GitHub
-  Actions
-* `spack/github-actions-buildcache <https://github.com/spack/github-actions-buildcache>`_ for

+        require: target=x86_64_v2
+    mirrors:
+      github_packages: oci://ghcr.io/<user>/<repo>
+
+And a GitHub action that sets up Spack, installs packages from the build cache
+or from sources, and pushes newly built binaries to the build cache:
+
+.. code-block:: yaml
+
+    name: Install Spack packages
+
+    on: push
+
+    env:
+      SPACK_COLOR: always
+
+    jobs:
+      example:
+        runs-on: ubuntu-22.04
+        steps:
+        - name: Checkout
+          uses: actions/checkout@v3
+
+        - name: Install Spack
+          run: |
+            git clone --depth=1 https://github.com/spack/spack.git
+            echo "$PWD/spack/bin/" >> "$GITHUB_PATH"
+
+        - name: Concretize
+          run: spack -e . concretize
+
+        - name: Install
+          run: spack -e . install --no-check-signature --fail-fast
+

+            spack -e . mirror set --oci-username <user> --oci-password "${{ secrets.GITHUB_TOKEN }}" github_packages
+            spack -e . buildcache push --base-image ubuntu:22.04 --unsigned --update-index github_packages
+            if: always()
+
+The first time this action runs, it will build the packages from source and
+push them to the build cache. Subsequent runs will pull the binaries from the
+build cache. The concretizer will ensure that prebuilt binaries are favored
+over source builds.
+
+The build cache entries appear in the GitHub Packages section of your repository,
+and contain instructions for pulling and running them with ``docker`` or ``podman``.
+
+----------
+Relocation
+----------
+
+Initial build and later installation do not necessarily happen at the same
+location. Spack provides a relocation capability and corrects for RPATHs and
+non-relocatable scripts. However, many packages compile paths into binary
+artifacts directly. In such cases, the build instructions of this package would
+need to be adjusted for better re-locatability.

+.. _build-settings:
+
+================================
+Package Settings (packages.yaml)
+================================
+
+Spack allows you to customize how your software is built through the
+``packages.yaml`` file.  Using it, you can make Spack prefer particular
+implementations of virtual dependencies (e.g., MPI or BLAS/LAPACK),
+or you can make it prefer to build with particular compilers.  You can
+also tell Spack to use *external* software installations already
+present on your system.
+
+At a high level, the ``packages.yaml`` file is structured like this:
+
+.. code-block:: yaml
+
+   packages:
+     package1:
+       # settings for package1
+     package2:
+       # settings for package2
+     # ...
+     all:
+       # settings that apply to all packages.
+
+So you can either set build preferences specifically for *one* package,
+or you can specify that certain settings should apply to *all* packages.
+The types of settings you can customize are described in detail below.
+
+Spack's build defaults are in the default
+``etc/spack/defaults/packages.yaml`` file.  You can override them in
+``~/.spack/packages.yaml`` or ``etc/spack/packages.yaml``. For more
+details on how this works, see :ref:`configuration-scopes`.
+
+.. _sec-external-packages:
+
+-----------------
+External Packages
+-----------------
+
+Spack can be configured to use externally-installed
+packages rather than building its own packages. This may be desirable
+if machines ship with system packages, such as a customized MPI
+that should be used instead of Spack building its own MPI.
+
+External packages are configured through the ``packages.yaml`` file.
+Here's an example of an external configuration:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+
+This example lists three installations of OpenMPI, one built with GCC,
+one built with GCC and debug information, and another built with Intel.
+If Spack is asked to build a package that uses one of these MPIs as a
+dependency, it will use the pre-installed OpenMPI in
+the given directory. Note that the specified path is the top-level
+install prefix, not the ``bin`` subdirectory.
+
+``packages.yaml`` can also be used to specify modules to load instead
+of the installation prefixes.  The following example says that module
+``CMake/3.7.2`` provides cmake version 3.7.2.
+
+.. code-block:: yaml
+
+   cmake:
+     externals:
+     - spec: cmake@3.7.2
+       modules:
+       - CMake/3.7.2
+
+Each ``packages.yaml`` begins with a ``packages:`` attribute, followed
+by a list of package names.  To specify externals, add an ``externals:``
+attribute under the package name, which lists externals.
+Each external should specify a ``spec:`` string that should be as
+well-defined as reasonably possible.  If a
+package lacks a spec component, such as missing a compiler or
+package version, then Spack will guess the missing component based
+on its most-favored packages, and it may guess incorrectly.
+
+Each package version and compiler listed in an external should
+have entries in Spack's packages and compiler configuration, even
+though the package and compiler may not ever be built.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Prevent packages from being built from sources
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Adding an external spec in ``packages.yaml`` allows Spack to use an external location,
+but it does not prevent Spack from building packages from sources. In the above example,
+Spack might choose for many valid reasons to start building and linking with the
+latest version of OpenMPI rather than continue using the pre-installed OpenMPI versions.
+
+To prevent this, the ``packages.yaml`` configuration also allows packages
+to be flagged as non-buildable.  The previous example could be modified to
+be:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+       buildable: False
+
+The addition of the ``buildable`` flag tells Spack that it should never build
+its own version of OpenMPI from sources, and it will instead always rely on a pre-built
+OpenMPI.
+
+.. note::
+
+   If ``concretizer:reuse`` is on (see :ref:`concretizer-options` for more information on that flag)
+   pre-built specs include specs already available from a local store, an upstream store, a registered
+   buildcache or specs marked as externals in ``packages.yaml``. If ``concretizer:reuse`` is off, only
+   external specs in ``packages.yaml`` are included in the list of pre-built specs.
+
+If an external module is specified as not buildable, then Spack will load the
+external module into the build environment which can be used for linking.
+
+The ``buildable`` does not need to be paired with external packages.
+It could also be used alone to forbid packages that may be
+buggy or otherwise undesirable.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Non-buildable virtual packages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Virtual packages in Spack can also be specified as not buildable, and
+external implementations can be provided. In the example above,
+OpenMPI is configured as not buildable, but Spack will often prefer
+other MPI implementations over the externally available OpenMPI. Spack
+can be configured with every MPI provider not buildable individually,
+but more conveniently:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       buildable: False
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+
+Spack can then use any of the listed external implementations of MPI
+to satisfy a dependency, and will choose depending on the compiler and
+architecture.
+
+In cases where the concretizer is configured to reuse specs, and other ``mpi`` providers
+(available via stores or buildcaches) are not wanted, Spack can be configured to require
+specs matching only the available externals:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       buildable: False
+       require:
+       - one_of: [
+           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64",
+           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug",
+           "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         ]
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+
+This configuration prevents any spec using MPI and originating from stores or buildcaches to be reused,
+unless it matches the requirements under ``packages:mpi:require``. For more information on requirements see
+:ref:`package-requirements`.
+
+.. _cmd-spack-external-find:
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Automatically Find External Packages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can run the :ref:`spack external find <spack-external-find>` command
+to search for system-provided packages and add them to ``packages.yaml``.
+After running this command your ``packages.yaml`` may include new entries:
+
+.. code-block:: yaml
+
+   packages:
+     cmake:
+       externals:
+       - spec: cmake@3.17.2
+         prefix: /usr
+
+Generally this is useful for detecting a small set of commonly-used packages;
+for now this is generally limited to finding build-only dependencies.
+Specific limitations include:
+
+* Packages are not discoverable by default: For a package to be
+  discoverable with ``spack external find``, it needs to add special
+  logic. See :ref:`here <make-package-findable>` for more details.
+* The logic does not search through module files, it can only detect
+  packages with executables defined in ``PATH``; you can help Spack locate
+  externals which use module files by loading any associated modules for
+  packages that you want Spack to know about before running
+  ``spack external find``.
+* Spack does not overwrite existing entries in the package configuration:
+  If there is an external defined for a spec at any configuration scope,
+  then Spack will not add a new external entry (``spack config blame packages``
+  can help locate all external entries).
+
+.. _package-requirements:
+
+--------------------
+Package Requirements
+--------------------
+
+Spack can be configured to always use certain compilers, package
+versions, and variants during concretization through package
+requirements.
+
+Package requirements are useful when you find yourself repeatedly
+specifying the same constraints on the command line, and wish that
+Spack respects these constraints whether you mention them explicitly
+or not. Another use case is specifying constraints that should apply
+to all root specs in an environment, without having to repeat the
+constraint everywhere.
+
+Apart from that, requirements config is more flexible than constraints
+on the command line, because it can specify constraints on packages
+*when they occur* as a dependency. In contrast, on the command line it
+is not possible to specify constraints on dependencies while also keeping
+those dependencies optional.
+
+^^^^^^^^^^^^^^^^^^^
+Requirements syntax
+^^^^^^^^^^^^^^^^^^^
+
+The package requirements configuration is specified in ``packages.yaml``,
+keyed by package name and expressed using the Spec syntax. In the simplest
+case you can specify attributes that you always want the package to have
+by providing a single spec string to ``require``:
+
+.. code-block:: yaml
+
+   packages:
+     libfabric:
+       require: "@1.13.2"
+
+In the above example, ``libfabric`` will always build with version 1.13.2. If you
+need to compose multiple configuration scopes ``require`` accepts a list of
+strings:
+
+.. code-block:: yaml
+
+   packages:
+     libfabric:
+       require:
+       - "@1.13.2"
+       - "%gcc"
+
+In this case ``libfabric`` will always build with version 1.13.2 **and** using GCC
+as a compiler.
+
+For more complex use cases, require accepts also a list of objects. These objects
+must have either a ``any_of`` or a ``one_of`` field, containing a list of spec strings,
+and they can optionally have a ``when`` and a ``message`` attribute:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       require:
+       - any_of: ["@4.1.5", "%gcc"]
+         message: "in this example only 4.1.5 can build with other compilers"
+
+``any_of`` is a list of specs. One of those specs must be satisfied
+and it is also allowed for the concretized spec to match more than one.
+In the above example, that means you could build ``openmpi@4.1.5%gcc``,
+``openmpi@4.1.5%clang`` or ``openmpi@3.9%gcc``, but
+not ``openmpi@3.9%clang``.
+
+If a custom message is provided, and the requirement is not satisfiable,
+Spack will print the custom error message:
+
+.. code-block:: console
+
+   $ spack spec openmpi@3.9%clang
+   ==> Error: in this example only 4.1.5 can build with other compilers
+
+We could express a similar requirement using the ``when`` attribute:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       require:
+       - any_of: ["%gcc"]
+         when: "@:4.1.4"
+         message: "in this example only 4.1.5 can build with other compilers"
+
+In the example above, if the version turns out to be 4.1.4 or less, we require the compiler to be GCC.
+For readability, Spack also allows a ``spec`` key accepting a string when there is only a single
+constraint:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       require:
+       - spec: "%gcc"
+         when: "@:4.1.4"
+         message: "in this example only 4.1.5 can build with other compilers"
+
+This code snippet and the one before it are semantically equivalent.
+
+Finally, instead of ``any_of`` you can use ``one_of`` which also takes a list of specs. The final
+concretized spec must match one and only one of them:
+
+.. code-block:: yaml
+
+   packages:
+     mpich:
+       require:
+       - one_of: ["+cuda", "+rocm"]
+
+In the example above, that means you could build ``mpich+cuda`` or ``mpich+rocm`` but not ``mpich+cuda+rocm``.
+
+.. note::
+
+   For ``any_of`` and ``one_of``, the order of specs indicates a
+   preference: items that appear earlier in the list are preferred
+   (note that these preferences can be ignored in favor of others).
+
+.. note::
+
+   When using a conditional requirement, Spack is allowed to actively avoid the triggering
+   condition (the ``when=...`` spec) if that leads to a concrete spec with better scores in
+   the optimization criteria. To check the current optimization criteria and their
+   priorities you can run ``spack solve zlib``.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Setting default requirements
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can also set default requirements for all packages under ``all``
+like this:
+
+.. code-block:: yaml
+
+   packages:
+     all:
+       require: '%clang'
+
+which means every spec will be required to use ``clang`` as a compiler.
+
+Note that in this case ``all`` represents a *default set of requirements* -
+if there are specific package requirements, then the default requirements
+under ``all`` are disregarded. For example, with a configuration like this:
+
+.. code-block:: yaml
+
+   packages:
+     all:
+       require: '%clang'
+     cmake:
+       require: '%gcc'
+
+Spack requires ``cmake`` to use ``gcc`` and all other nodes (including ``cmake``
+dependencies) to use ``clang``.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Setting requirements on virtual specs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A requirement on a virtual spec applies whenever that virtual is present in the DAG.
+This can be useful for fixing which virtual provider you want to use:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       require: 'mvapich2 %gcc'
+
+With the configuration above the only allowed ``mpi`` provider is ``mvapich2 %gcc``.
+
+Requirements on the virtual spec and on the specific provider are both applied, if
+present. For instance with a configuration like:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       require: 'mvapich2 %gcc'
+     mvapich2:

+
+you will use ``mvapich2~cuda %gcc`` as an ``mpi`` provider.
+
+.. _package-preferences:
+
+-------------------
+Package Preferences
+-------------------
+
+In some cases package requirements can be too strong, and package
+preferences are the better option. Package preferences do not impose
+constraints on packages for particular versions or variants values,
+they rather only set defaults -- the concretizer is free to change
+them if it must due to other constraints. Also note that package
+preferences are of lower priority than reuse of already installed
+packages.
+
+Here's an example ``packages.yaml`` file that sets preferred packages:
+
+.. code-block:: yaml
+
+   packages:
+     opencv:
+       compiler: [gcc@4.9]
+       variants: +debug
+     gperftools:
+       version: [2.2, 2.4, 2.3]
+     all:
+       compiler: [gcc@4.4.7, 'gcc@4.6:', intel, clang, pgi]
+       target: [sandybridge]
+       providers:
+         mpi: [mvapich2, mpich, openmpi]
+
+At a high level, this example is specifying how packages are preferably
+concretized.  The opencv package should prefer using GCC 4.9 and
+be built with debug options.  The gperftools package should prefer version
+2.2 over 2.4.  Every package on the system should prefer mvapich2 for
+its MPI and GCC 4.4.7 (except for opencv, which overrides this by preferring GCC 4.9).
+These options are used to fill in implicit defaults.  Any of them can be overwritten
+on the command line if explicitly requested.
+
+Package preferences accept the follow keys or components under
+the specific package (or ``all``) section: ``compiler``, ``variants``,
+``version``, ``providers``, and ``target``.  Each component has an
+ordered list of spec ``constraints``, with earlier entries in the
+list being preferred over later entries.
+
+Sometimes a package installation may have constraints that forbid
+the first concretization rule, in which case Spack will use the first
+legal concretization rule.  Going back to the example, if a user
+requests gperftools 2.3 or later, then Spack will install version 2.4
+as the 2.4 version of gperftools is preferred over 2.3.
+
+An explicit concretization rule in the preferred section will always
+take preference over unlisted concretizations.  In the above example,
+xlc isn't listed in the compiler list.  Every listed compiler from
+gcc to pgi will thus be preferred over the xlc compiler.
+
+The syntax for the ``provider`` section differs slightly from other
+concretization rules.  A provider lists a value that packages may
+``depends_on`` (e.g, MPI) and a list of rules for fulfilling that
+dependency.
+
+.. _package_permissions:
+
+-------------------
+Package Permissions
+-------------------
+
+Spack can be configured to assign permissions to the files installed
+by a package.
+
+In the ``packages.yaml`` file under ``permissions``, the attributes
+``read``, ``write``, and ``group`` control the package
+permissions. These attributes can be set per-package, or for all
+packages under ``all``. If permissions are set under ``all`` and for a
+specific package, the package-specific settings take precedence.
+
+The ``read`` and ``write`` attributes take one of ``user``, ``group``,
+and ``world``.
+
+.. code-block:: yaml
+
+  packages:
+    all:
+      permissions:
+        write: group
+        group: spack
+    my_app:
+      permissions:
+        read: group
+        group: my_team
+
+The permissions settings describe the broadest level of access to
+installations of the specified packages. The execute permissions of
+the file are set to the same level as read permissions for those files
+that are executable. The default setting for ``read`` is ``world``,
+and for ``write`` is ``user``. In the example above, installations of
+``my_app`` will be installed with user and group permissions but no
+world permissions, and owned by the group ``my_team``. All other
+packages will be installed with user and group write privileges, and
+world read privileges. Those packages will be owned by the group
+``spack``.
+
+The ``group`` attribute assigns a Unix-style group to a package. All
+files installed by the package will be owned by the assigned group,
+and the sticky group bit will be set on the install prefix and all
+directories inside the install prefix. This will ensure that even
+manually placed files within the install prefix are owned by the
+assigned group. If no group is assigned, Spack will allow the OS
+default behavior to go as expected.
+
+----------------------------
+Assigning Package Attributes
+----------------------------
+
+You can assign class-level attributes in the configuration:
+
+.. code-block:: yaml
+
+  packages:
+    mpileaks:
+      # Override existing attributes
+      url: http://www.somewhereelse.com/mpileaks-1.0.tar.gz
+      # ... or add new ones
+      x: 1
+
+Attributes set this way will be accessible to any method executed
+in the package.py file (e.g. the ``install()`` method). Values for these
+attributes may be any value parseable by yaml.
+
+These can only be applied to specific packages, not "all" or
+virtual packages.

 Container Images
 ================
 
-Spack :ref:`environments` can easily be turned into container images. This page
-outlines two ways in which this can be done:
-
-1. By installing the environment on the host system, and copying the installations
-   into the container image. This approach does not require any tools like Docker
-   or Singularity to be installed.
-2. By generating a Docker or Singularity recipe that can be used to build the
-   container image. In this approach, Spack builds the software inside the
-   container runtime, not on the host system.
-
-The first approach is easiest if you already have an installed environment,
-the second approach gives more control over the container image.
-
----------------------------
-From existing installations
----------------------------
-
-If you already have a Spack environment installed on your system, you can
-share the binaries as an OCI compatible container image. To get started you
-just have to configure and OCI registry and run ``spack buildcache push``.
-
-.. code-block:: console
-  
-   # Create and install an environment in the current directory
-   spack env create -d .
-   spack -e . add pkg-a pkg-b
-   spack -e . install
-
-   # Configure the registry
-   spack -e . mirror add --oci-username ... --oci-password ... container-registry oci://example.com/name/image
-
-   # Push the image
-   spack -e . buildcache push --update-index --base-image ubuntu:22.04 --tag my_env container-registry
-
-The resulting container image can then be run as follows:
-
-.. code-block:: console
-
-   $ docker run -it example.com/name/image:my_env
-
-The image generated by Spack consists of the specified base image with each package from the
-environment as a separate layer on top. The image is minimal by construction, it only contains the
-environment roots and its runtime dependencies.
-
-.. note::
-
-  When using registries like GHCR and Docker Hub, the ``--oci-password`` flag is not
-  the password for your account, but a personal access token you need to generate separately.
-
-The specified ``--base-image`` should have a libc that is compatible with the host system.
-For example if your host system is Ubuntu 20.04, you can use ``ubuntu:20.04``, ``ubuntu:22.04``
-or newer: the libc in the container image must be at least the version of the host system,
-assuming ABI compatibility. It is also perfectly fine to use a completely different
-Linux distribution as long as the libc is compatible.
-
-For convenience, Spack also turns the OCI registry into a :ref:`build cache <binary_caches_oci>`,
-so that future ``spack install`` of the environment will simply pull the binaries from the
-registry instead of doing source builds. The flag ``--update-index`` is needed to make Spack
-take the build cache into account when concretizing.
-
-.. note::
-
-  When generating container images in CI, the approach above is recommended when CI jobs
-  already run in a sandboxed environment. You can simply use ``spack`` directly
-  in the CI job and push the resulting image to a registry. Subsequent CI jobs should
-  run faster because Spack can install from the same registry instead of rebuilding from
-  sources.
-
----------------------------------------------
-Generating recipes for Docker and Singularity
----------------------------------------------
-
-Apart from copying existing installations into container images, Spack can also
-generate recipes for container images. This is useful if you want to run Spack
-itself in a sandboxed environment instead of on the host system.
-
-Since recipes need a little bit more boilerplate than
+Spack :ref:`environments` are a great tool to create container images, but
+preparing one that is suitable for production requires some more boilerplate
+than just:
 
 .. code-block:: docker
 
    COPY spack.yaml /environment
    RUN spack -e /environment install
 
-Spack provides a command to generate customizable recipes for container images. Customizations
-include minimizing the size of the image, installing packages in the base image using the system
-package manager, and setting up a proper entrypoint to run the image.
+Additional actions may be needed to minimize the size of the
+container, or to update the system software that is installed in the base
+image, or to set up a proper entrypoint to run the image. These tasks are
+usually both necessary and repetitive, so Spack comes with a command
+to generate recipes for container images starting from a ``spack.yaml``.

-If you have questions that are not answered here, feel free to ask on
-`Slack <https://slack.spack.io>`_ or `GitHub Discussions

-.. _faq-concretizer-precedence:
-
------------------------------------------------------
-Why does Spack pick particular versions and variants?
------------------------------------------------------
-
-This question comes up in a variety of forms:
-
- 1. Why does Spack seem to ignore my package preferences from ``packages.yaml`` config?
- 2. Why does Spack toggle a variant instead of using the default from the ``package.py`` file?
-
-The short answer is that Spack always picks an optimal configuration
-based on a complex set of criteria\ [#f1]_. These criteria are more nuanced
-than always choosing the latest versions or default variants.
-
-.. note::
-
-    As a rule of thumb: requirements + constraints > reuse > preferences > defaults.
-
-The following set of criteria (from lowest to highest precedence) explain
-common cases where concretization output may seem surprising at first.
-
-1. :ref:`Package preferences <package-preferences>` configured in ``packages.yaml``
-   override variant defaults from ``package.py`` files, and influence the optimal
-   ordering of versions. Preferences are specified as follows:
-
-   .. code-block:: yaml
-
-      packages:
-        foo:
-          version: [1.0, 1.1]
-          variants: ~mpi
-
-2. :ref:`Reuse concretization <concretizer-options>` configured in ``concretizer.yaml``
-   overrides preferences, since it's typically faster to reuse an existing spec than to
-   build a preferred one from sources. When build caches are enabled, specs may be reused
-   from a remote location too. Reuse concretization is configured as follows:
-
-   .. code-block:: yaml
-
-      concretizer:
-        reuse: dependencies  # other options are 'true' and 'false'
-
-3. :ref:`Package requirements <package-requirements>` configured in ``packages.yaml``,
-   and constraints from the command line as well as ``package.py`` files override all
-   of the above. Requirements are specified as follows:
-
-   .. code-block:: yaml
-
-      packages:
-        foo:
-          require:
-          - "@1.2: +mpi"
-
-Requirements and constraints restrict the set of possible solutions, while reuse
-behavior and preferences influence what an optimal solution looks like.

-Lmod and Environment Modules under the ``autoload: direct`` config option. The former system has
-builtin support through the ``depends_on`` function, the latter simply uses a ``module load``
-statement. Both module systems (at least in newer versions) do reference counting, so that if a
-module is loaded by two different modules, it will only be unloaded after the others are.
-
-The ``autoload`` key accepts the values ``none``, ``direct``, and ``all``. To disable it, use
-``none``, and to enable, it's best to stick to ``direct``, which only autoloads the direct link and
-run type dependencies, relying on recursive autoloading to load the rest.
-
-A common complaint about autoloading is the large number of modules that are visible to the user.
-Spack has a solution for this as well: ``hide_implicits: true``. This ensures that only those
-packages you've explicitly installed are exposed by ``module avail``, but still allows for
-autoloading of hidden dependencies. Lmod should support hiding implicits in general, while
-Environment Modules requires version 4.7 or higher.
-
-.. note::
-   If supported by your module system, we highly encourage the following configuration that enables
-   autoloading and hiding of implicits. It ensures all runtime variables are set correctly,

-================================
-Package Settings (packages.yaml)
-================================
-
-Spack allows you to customize how your software is built through the
-``packages.yaml`` file.  Using it, you can make Spack prefer particular
-implementations of virtual dependencies (e.g., MPI or BLAS/LAPACK),
-or you can make it prefer to build with particular compilers.  You can
-also tell Spack to use *external* software installations already
-present on your system.
-
-At a high level, the ``packages.yaml`` file is structured like this:
-
-.. code-block:: yaml
-
-   packages:
-     package1:
-       # settings for package1
-     package2:
-       # settings for package2
-     # ...
-     all:
-       # settings that apply to all packages.
-
-So you can either set build preferences specifically for *one* package,
-or you can specify that certain settings should apply to *all* packages.
-The types of settings you can customize are described in detail below.
-
-Spack's build defaults are in the default
-``etc/spack/defaults/packages.yaml`` file.  You can override them in
-``~/.spack/packages.yaml`` or ``etc/spack/packages.yaml``. For more
-details on how this works, see :ref:`configuration-scopes`.
-
-.. _sec-external-packages:
-
------------------
-External Packages
------------------
-
-Spack can be configured to use externally-installed
-packages rather than building its own packages. This may be desirable
-if machines ship with system packages, such as a customized MPI
-that should be used instead of Spack building its own MPI.
-
-External packages are configured through the ``packages.yaml`` file.
-Here's an example of an external configuration:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-
-This example lists three installations of OpenMPI, one built with GCC,
-one built with GCC and debug information, and another built with Intel.
-If Spack is asked to build a package that uses one of these MPIs as a
-dependency, it will use the pre-installed OpenMPI in
-the given directory. Note that the specified path is the top-level
-install prefix, not the ``bin`` subdirectory.
-
-``packages.yaml`` can also be used to specify modules to load instead
-of the installation prefixes.  The following example says that module
-``CMake/3.7.2`` provides cmake version 3.7.2.
-
-.. code-block:: yaml
-
-   cmake:
-     externals:
-     - spec: cmake@3.7.2
-       modules:
-       - CMake/3.7.2
-
-Each ``packages.yaml`` begins with a ``packages:`` attribute, followed
-by a list of package names.  To specify externals, add an ``externals:``
-attribute under the package name, which lists externals.
-Each external should specify a ``spec:`` string that should be as
-well-defined as reasonably possible.  If a
-package lacks a spec component, such as missing a compiler or
-package version, then Spack will guess the missing component based
-on its most-favored packages, and it may guess incorrectly.
-
-Each package version and compiler listed in an external should
-have entries in Spack's packages and compiler configuration, even
-though the package and compiler may not ever be built.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Extra attributes for external packages
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Sometimes external packages require additional attributes to be used
-effectively. This information can be defined on a per-package basis
-and stored in the ``extra_attributes`` section of the external package
-configuration. In addition to per-package information, this section
-can be used to define environment modifications to be performed
-whenever the package is used. For example, if an external package is
-built without ``rpath`` support, it may require ``LD_LIBRARY_PATH``
-settings to find its dependencies. This could be configured as
-follows:
-
-.. code-block:: yaml
-
-   packages:
-     mpich:
-       externals:
-       - spec: mpich@3.3 %clang@12.0.0 +hwloc
-         prefix: /path/to/mpich
-         extra_attributes:
-           environment:
-             prepend_path:
-               LD_LIBRARY_PATH: /path/to/hwloc/lib64
-
-See :ref:`configuration_environment_variables` for more information on
-how to configure environment modifications in Spack config files.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Prevent packages from being built from sources
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Adding an external spec in ``packages.yaml`` allows Spack to use an external location,
-but it does not prevent Spack from building packages from sources. In the above example,
-Spack might choose for many valid reasons to start building and linking with the
-latest version of OpenMPI rather than continue using the pre-installed OpenMPI versions.
-
-To prevent this, the ``packages.yaml`` configuration also allows packages
-to be flagged as non-buildable.  The previous example could be modified to
-be:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-       buildable: False
-
-The addition of the ``buildable`` flag tells Spack that it should never build
-its own version of OpenMPI from sources, and it will instead always rely on a pre-built
-OpenMPI.
-
-.. note::
-
-   If ``concretizer:reuse`` is on (see :ref:`concretizer-options` for more information on that flag)
-   pre-built specs include specs already available from a local store, an upstream store, a registered
-   buildcache or specs marked as externals in ``packages.yaml``. If ``concretizer:reuse`` is off, only
-   external specs in ``packages.yaml`` are included in the list of pre-built specs.
-
-If an external module is specified as not buildable, then Spack will load the
-external module into the build environment which can be used for linking.
-
-The ``buildable`` does not need to be paired with external packages.
-It could also be used alone to forbid packages that may be
-buggy or otherwise undesirable.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Non-buildable virtual packages
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Virtual packages in Spack can also be specified as not buildable, and
-external implementations can be provided. In the example above,
-OpenMPI is configured as not buildable, but Spack will often prefer
-other MPI implementations over the externally available OpenMPI. Spack
-can be configured with every MPI provider not buildable individually,
-but more conveniently:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       buildable: False
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-
-Spack can then use any of the listed external implementations of MPI
-to satisfy a dependency, and will choose depending on the compiler and
-architecture.
-
-In cases where the concretizer is configured to reuse specs, and other ``mpi`` providers
-(available via stores or buildcaches) are not wanted, Spack can be configured to require
-specs matching only the available externals:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       buildable: False
-       require:
-       - one_of: [
-           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64",
-           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug",
-           "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         ]
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-
-This configuration prevents any spec using MPI and originating from stores or buildcaches to be reused,
-unless it matches the requirements under ``packages:mpi:require``. For more information on requirements see
-:ref:`package-requirements`.
-
-.. _cmd-spack-external-find:
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Automatically Find External Packages
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can run the :ref:`spack external find <spack-external-find>` command
-to search for system-provided packages and add them to ``packages.yaml``.
-After running this command your ``packages.yaml`` may include new entries:
-
-.. code-block:: yaml
-
-   packages:
-     cmake:
-       externals:
-       - spec: cmake@3.17.2
-         prefix: /usr
-
-Generally this is useful for detecting a small set of commonly-used packages;
-for now this is generally limited to finding build-only dependencies.
-Specific limitations include:
-
-* Packages are not discoverable by default: For a package to be
-  discoverable with ``spack external find``, it needs to add special
-  logic. See :ref:`here <make-package-findable>` for more details.
-* The logic does not search through module files, it can only detect
-  packages with executables defined in ``PATH``; you can help Spack locate
-  externals which use module files by loading any associated modules for
-  packages that you want Spack to know about before running
-  ``spack external find``.
-* Spack does not overwrite existing entries in the package configuration:
-  If there is an external defined for a spec at any configuration scope,
-  then Spack will not add a new external entry (``spack config blame packages``
-  can help locate all external entries).
-
-.. _package-requirements:
-
---------------------
-Package Requirements
---------------------
-
-Spack can be configured to always use certain compilers, package
-versions, and variants during concretization through package
-requirements.
-
-Package requirements are useful when you find yourself repeatedly
-specifying the same constraints on the command line, and wish that
-Spack respects these constraints whether you mention them explicitly
-or not. Another use case is specifying constraints that should apply
-to all root specs in an environment, without having to repeat the
-constraint everywhere.
-
-Apart from that, requirements config is more flexible than constraints
-on the command line, because it can specify constraints on packages
-*when they occur* as a dependency. In contrast, on the command line it
-is not possible to specify constraints on dependencies while also keeping
-those dependencies optional.

-keyed by package name and expressed using the Spec syntax. In the simplest
-case you can specify attributes that you always want the package to have
-by providing a single spec string to ``require``:
-
-.. code-block:: yaml
-
-   packages:
-     libfabric:
-       require: "@1.13.2"
-
-In the above example, ``libfabric`` will always build with version 1.13.2. If you
-need to compose multiple configuration scopes ``require`` accepts a list of
-strings:
-
-.. code-block:: yaml
-
-   packages:
-     libfabric:
-       require:
-       - "@1.13.2"
-       - "%gcc"
-
-In this case ``libfabric`` will always build with version 1.13.2 **and** using GCC
-as a compiler.
-
-For more complex use cases, require accepts also a list of objects. These objects
-must have either a ``any_of`` or a ``one_of`` field, containing a list of spec strings,
-and they can optionally have a ``when`` and a ``message`` attribute:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       require:
-       - any_of: ["@4.1.5", "%gcc"]
-         message: "in this example only 4.1.5 can build with other compilers"
-
-``any_of`` is a list of specs. One of those specs must be satisfied
-and it is also allowed for the concretized spec to match more than one.
-In the above example, that means you could build ``openmpi@4.1.5%gcc``,
-``openmpi@4.1.5%clang`` or ``openmpi@3.9%gcc``, but
-not ``openmpi@3.9%clang``.
-
-If a custom message is provided, and the requirement is not satisfiable,
-Spack will print the custom error message:
-
-.. code-block:: console
-
-   $ spack spec openmpi@3.9%clang
-   ==> Error: in this example only 4.1.5 can build with other compilers
-
-We could express a similar requirement using the ``when`` attribute:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       require:
-       - any_of: ["%gcc"]
-         when: "@:4.1.4"
-         message: "in this example only 4.1.5 can build with other compilers"
-
-In the example above, if the version turns out to be 4.1.4 or less, we require the compiler to be GCC.
-For readability, Spack also allows a ``spec`` key accepting a string when there is only a single
-constraint:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       require:
-       - spec: "%gcc"
-         when: "@:4.1.4"
-         message: "in this example only 4.1.5 can build with other compilers"
-
-This code snippet and the one before it are semantically equivalent.
-
-Finally, instead of ``any_of`` you can use ``one_of`` which also takes a list of specs. The final
-concretized spec must match one and only one of them:
-
-.. code-block:: yaml
-
-   packages:
-     mpich:
-       require:
-       - one_of: ["+cuda", "+rocm"]
-
-In the example above, that means you could build ``mpich+cuda`` or ``mpich+rocm`` but not ``mpich+cuda+rocm``.
-
-.. note::
-
-   For ``any_of`` and ``one_of``, the order of specs indicates a
-   preference: items that appear earlier in the list are preferred
-   (note that these preferences can be ignored in favor of others).
-
-.. note::
-
-   When using a conditional requirement, Spack is allowed to actively avoid the triggering
-   condition (the ``when=...`` spec) if that leads to a concrete spec with better scores in
-   the optimization criteria. To check the current optimization criteria and their
-   priorities you can run ``spack solve zlib``.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Setting default requirements
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can also set default requirements for all packages under ``all``
-like this:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require: '%clang'
-
-which means every spec will be required to use ``clang`` as a compiler.
-
-Requirements on variants for all packages are possible too, but note that they
-are only enforced for those packages that define these variants, otherwise they
-are disregarded. For example:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require:
-       - "+shared"
-       - "+cuda"
-
-will just enforce ``+shared`` on ``zlib``, which has a boolean ``shared`` variant but
-no ``cuda`` variant.
-
-Constraints in a single spec literal are always considered as a whole, so in a case like:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require: "+shared +cuda"
-
-the default requirement will be enforced only if a package has both a ``cuda`` and
-a ``shared`` variant, and will never be partially enforced.
-
-Finally, ``all`` represents a *default set of requirements* -
-if there are specific package requirements, then the default requirements
-under ``all`` are disregarded. For example, with a configuration like this:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require:
-       - 'build_type=Debug'
-       - '%clang'
-     cmake:
-       require:
-       - 'build_type=Debug'
-       - '%gcc'
-
-Spack requires ``cmake`` to use ``gcc`` and all other nodes (including ``cmake``
-dependencies) to use ``clang``. If enforcing ``build_type=Debug`` is needed also
-on ``cmake``, it must be repeated in the specific ``cmake`` requirements.
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Setting requirements on virtual specs
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-A requirement on a virtual spec applies whenever that virtual is present in the DAG.
-This can be useful for fixing which virtual provider you want to use:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       require: 'mvapich2 %gcc'
-
-With the configuration above the only allowed ``mpi`` provider is ``mvapich2 %gcc``.
-
-Requirements on the virtual spec and on the specific provider are both applied, if
-present. For instance with a configuration like:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       require: 'mvapich2 %gcc'
-     mvapich2:
-       require: '~cuda'
-
-you will use ``mvapich2~cuda %gcc`` as an ``mpi`` provider.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Conflicts and strong preferences
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If the semantic of requirements is too strong, you can also express "strong preferences" and "conflicts"
-from configuration files:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       prefer:
-       - '%clang'
-       conflict:
-       - '+shared'
-
-The ``prefer`` and ``conflict`` sections can be used whenever a ``require`` section is allowed.
-The argument is always a list of constraints, and each constraint can be either a simple string,
-or a more complex object:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       conflict:
-       - spec: '%clang'
-         when: 'target=x86_64_v3'
-         message: 'reason why clang cannot be used'
-
-The ``spec`` attribute is mandatory, while both ``when`` and ``message`` are optional.
-
-.. note::
-
-   Requirements allow for expressing both "strong preferences" and "conflicts".
-   The syntax for doing so, though, may not be immediately clear. For
-   instance, if we want to prevent any package from using ``%clang``, we can set:
-
-   .. code-block:: yaml
-
-      packages:
-        all:
-          require:
-          - one_of: ['%clang', '@:']
-
-   Since only one of the requirements must hold, and ``@:`` is always true, the rule above is
-   equivalent to a conflict. For "strong preferences" we need to substitute the ``one_of`` policy
-   with ``any_of``.
-
-
-
-.. _package-preferences:
-
--------------------
-Package Preferences
--------------------
-
-In some cases package requirements can be too strong, and package
-preferences are the better option. Package preferences do not impose
-constraints on packages for particular versions or variants values,
-they rather only set defaults. The concretizer is free to change
-them if it must, due to other constraints, and also prefers reusing
-installed packages over building new ones that are a better match for
-preferences.
-
-.. seealso::
-
-   FAQ: :ref:`Why does Spack pick particular versions and variants? <faq-concretizer-precedence>`
-
-
-Most package preferences (``compilers``, ``target`` and ``providers``)
-can only be set globally under the ``all`` section of ``packages.yaml``:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       compiler: [gcc@12.2.0, clang@12:, oneapi@2023:]
-       target: [x86_64_v3]
-       providers:
-         mpi: [mvapich2, mpich, openmpi]
-
-These preferences override Spack's default and effectively reorder priorities
-when looking for the best compiler, target or virtual package provider. Each
-preference takes an ordered list of spec constraints, with earlier entries in
-the list being preferred over later entries.
-
-In the example above all packages prefer to be compiled with ``gcc@12.2.0``,
-to target the ``x86_64_v3`` microarchitecture and to use ``mvapich2`` if they
-depend on ``mpi``.
-
-The ``variants`` and ``version`` preferences can be set under
-package specific sections of the ``packages.yaml`` file:
-
-.. code-block:: yaml
-
-   packages:
-     opencv:
-       variants: +debug
-     gperftools:
-       version: [2.2, 2.4, 2.3]
-
-In this case, the preference for ``opencv`` is to build with debug options, while
-``gperftools`` prefers version 2.2 over 2.4.
-
-Any preference can be overwritten on the command line if explicitly requested.
-
-Preferences cannot overcome explicit constraints, as they only set a preferred
-ordering among homogeneous attribute values. Going back to the example, if
-``gperftools@2.3:`` was requested, then Spack will install version 2.4
-since the most preferred version 2.2 is prohibited by the version constraint.
-
-.. _package_permissions:
-
--------------------
-Package Permissions
--------------------
-
-Spack can be configured to assign permissions to the files installed
-by a package.
-
-In the ``packages.yaml`` file under ``permissions``, the attributes
-``read``, ``write``, and ``group`` control the package
-permissions. These attributes can be set per-package, or for all
-packages under ``all``. If permissions are set under ``all`` and for a
-specific package, the package-specific settings take precedence.
-
-The ``read`` and ``write`` attributes take one of ``user``, ``group``,
-and ``world``.
-
-.. code-block:: yaml
-
-  packages:
-    all:
-      permissions:
-        write: group
-        group: spack
-    my_app:
-      permissions:
-        read: group
-        group: my_team
-
-The permissions settings describe the broadest level of access to
-installations of the specified packages. The execute permissions of
-the file are set to the same level as read permissions for those files
-that are executable. The default setting for ``read`` is ``world``,
-and for ``write`` is ``user``. In the example above, installations of
-``my_app`` will be installed with user and group permissions but no
-world permissions, and owned by the group ``my_team``. All other
-packages will be installed with user and group write privileges, and
-world read privileges. Those packages will be owned by the group
-``spack``.
-
-The ``group`` attribute assigns a Unix-style group to a package. All
-files installed by the package will be owned by the assigned group,
-and the sticky group bit will be set on the install prefix and all
-directories inside the install prefix. This will ensure that even
-manually placed files within the install prefix are owned by the
-assigned group. If no group is assigned, Spack will allow the OS
-default behavior to go as expected.
-
-.. _assigning-package-attributes:
-
-----------------------------
-Assigning Package Attributes
-----------------------------
-
-You can assign class-level attributes in the configuration:
-
-.. code-block:: yaml
-
-  packages:
-    mpileaks:
-      package_attributes:
-        # Override existing attributes
-        url: http://www.somewhereelse.com/mpileaks-1.0.tar.gz
-        # ... or add new ones
-        x: 1
-
-Attributes set this way will be accessible to any method executed
-in the package.py file (e.g. the ``install()`` method). Values for these
-attributes may be any value parseable by yaml.
-
-These can only be applied to specific packages, not "all" or
-virtual packages.

-Providing multiple virtuals simultaneously
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Packages can provide more than one virtual dependency. Sometimes, due to implementation details,
-there are subsets of those virtuals that need to be provided together by the same package.
-
-A well-known example is ``openblas``, which provides both the ``lapack`` and ``blas`` API in a single ``libopenblas``
-library. A package that needs ``lapack`` and ``blas`` must either use ``openblas`` to provide both, or not use
-``openblas`` at all. It cannot pick one or the other.
-
-To express this constraint in a package, the two virtual dependencies must be listed in the same ``provides`` directive:
-
-.. code-block:: python
-
-   provides('blas', 'lapack')
-
-This makes it impossible to select ``openblas`` as a provider for one of the two
-virtual dependencies and not for the other. If you try to, Spack will report an error:
