 abstract: >-
-  Large HPC centers spend considerable time supporting software for thousands of users, but the
-  complexity of HPC software is quickly outpacing the capabilities of existing software management
-  tools. Scientific applications require specific versions of compilers, MPI, and other dependency
-  libraries, so using a single, standard software stack is infeasible. However, managing many

-  Spack provides a novel, re- cursive specification syntax to invoke parametric builds of packages
-  and dependencies. It allows any number of builds to coexist on the same system, and it ensures
-  that installed packages can find their dependencies, regardless of the environment. We show

--------------------
-
-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:

 OCI / Docker V2 registries as build cache

@@ -321,13 +251,87 @@ 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.
 
+A typical workflow is to include a ``spack.yaml`` environment in your repository

+cache to use under ``mirrors``:
+
+.. code-block:: yaml
+

+
+A GitHub action can then be used to install the packages and push them to the

 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``.

+.. seealso::
+
+  This page is a reference for generating recipes to build container images.
+  It means that your environment is built from scratch inside the container

-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Autoloading and hiding dependencies
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-A module file should set the variables that are needed for an application to work. But since an
-application often has many dependencies, where should all the environment variables for those be
-set? In Spack the rule is that each package sets the runtime variables that are needed by the
-package itself, and no more. This way, dependencies can be loaded standalone too, and duplication
-of environment variables is avoided.
-
-That means however that if you want to use an application, you need to load the modules for all its
-dependencies. Of course this is not something you would want users to do manually.
-
-Since Spack knows the dependency graph of every package, it can easily generate module files that
-automatically load the modules for its dependencies recursively. It is enabled by default for both
-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``: no autoloading
-  * ``run``: autoload direct *run* type dependencies
-  * ``direct``: autoload direct *link and run* type dependencies
-  * ``all``: autoload all dependencies
-
-In case of ``run`` and ``direct``, a ``module load`` triggers a recursive load.
-
-The ``direct`` option is most correct: there are cases where pure link dependencies need to set
-variables for themselves, or need to have variables of their own dependencies set.
-
-In practice however, ``run`` is often sufficient, and may make ``module load`` snappier.
-
-The ``all`` option is discouraged and seldomly used.
-
-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,
-   including those for dependencies, without overwhelming the user with a large number of available
-   modules. Further, it makes it easier to get readable module names without collisions, see the

 ^^^^^^^^^^^^^^^^^^
 Version comparison
 ^^^^^^^^^^^^^^^^^^
 
-Spack imposes a generic total ordering on the set of versions,
-independently from the package they are associated with.
-
 Most Spack versions are numeric, a tuple of integers; for example,
-``0.1``, ``6.96`` or ``1.2.3.1``. In this very basic case, version
-comparison is lexicographical on the numeric components:
-``1.2 < 1.2.1 < 1.2.2 < 1.10``.
+``0.1``, ``6.96`` or ``1.2.3.1``.  Spack knows how to compare and sort
+numeric versions.
 
-Spack can also supports string components such as ``1.1.1a`` and
-``1.y.0``. String components are considered less than numeric
-components, so ``1.y.0 < 1.0``. This is for consistency with
-`RPM <https://bugzilla.redhat.com/show_bug.cgi?id=50977>`_. String
-components do not have to be separated by dots or any other delimiter.
-So, the contrived version ``1y0`` is identical to ``1.y.0``.
+Some Spack versions involve slight extensions of numeric syntax; for
+example, ``py-sphinx-rtd-theme@=0.1.10a0``.  In this case, numbers are
+always considered to be "newer" than letters.  This is for consistency
+with `RPM <https://bugzilla.redhat.com/show_bug.cgi?id=50977>`_.
 
-Pre-release suffixes also contain string parts, but they are handled
-in a special way. For example ``1.2.3alpha1`` is parsed as a pre-release
-of the version ``1.2.3``. This allows Spack to order it before the
-actual release: ``1.2.3alpha1 < 1.2.3``. Spack supports alpha, beta and
-release candidate suffixes: ``1.2alpha1 < 1.2beta1 < 1.2rc1 < 1.2``. Any
-suffix not recognized as a pre-release is treated as an ordinary
-string component, so ``1.2 < 1.2-mysuffix``.
+Spack versions may also be arbitrary non-numeric strings, for example
+``develop``, ``master``, ``local``.
 
-Finally, there are a few special string components that are considered
-"infinity versions". They include ``develop``, ``main``, ``master``,
-``head``, ``trunk``, and ``stable``. For example: ``1.2 < develop``.
-These are useful for specifying the most recent development version of
-a package (often a moving target like a git branch), without assigning
-a specific version number. Infinity versions are not automatically used when determining the latest version of a package unless explicitly required by another package or user.
-
-More formally, the order on versions is defined as follows. A version
-string is split into a list of components based on delimiters such as
-``.`` and ``-`` and string boundaries. The components are split into
-the **release** and a possible **pre-release** (if the last component
-is numeric and the second to last is a string ``alpha``, ``beta`` or ``rc``).

-cpuid.py
-========
-
-Now, this is silly!
-
-Pure Python library for accessing information about x86 processors
-by querying the [CPUID](http://en.wikipedia.org/wiki/CPUID)
-instruction. Well, not exactly pure Python...
-
-It works by allocating a small piece of virtual memory, copying
-a raw x86 function to that memory, giving the memory execute
-permissions and then calling the memory as a function. The injected
-function executes the CPUID instruction and copies the result back
-to a ctypes.Structure where is can be read by Python.
-
-It should work fine on both 32 and 64 bit versions of Windows and Linux
-running x86 processors. Apple OS X and other BSD systems should also work,
-not tested though...
-
-
-Why?
-----
-For poops and giggles. Plus, having access to a low-level feature
-without having to compile a C wrapper is pretty neat.
-
-
-Examples
---------
-Getting info with eax=0:
-
-    import cpuid
-
-    q = cpuid.CPUID()
-    eax, ebx, ecx, edx = q(0)
-
-Running the files:
-
-    $ python example.py 
-    Vendor ID : GenuineIntel
