@@ -124,61 +124,36 @@ Spack provides two ways of bootstrapping ``clingo``: from pre-built binaries
(default), or from sources. The fastest way to get started is to bootstrap from
pre-built binaries.
.. note::
When bootstrapping from pre-built binaries, Spack currently requires
``patchelf`` on Linux and ``otool`` on macOS. If ``patchelf`` is not in the
``PATH``, Spack will build it from sources, and a C++ compiler is required.
The first time you concretize a spec, Spack will bootstrap in the background:
The first time you concretize a spec, Spack will bootstrap automatically:

After this command you'll see that ``clingo`` has been installed for Spack's own use:

$ spack find -b

Subsequent calls to the concretizer will then be much faster:
.. code-block:: console
$ time spack spec zlib

If for security concerns you cannot bootstrap ``clingo`` from pre-built
binaries, you have to mark this bootstrapping method as untrusted. This makes
Spack fall back to bootstrapping from sources:
binaries, you have to disable fetching the binaries we generated with Github Actions.
.. code-block:: console
$ spack bootstrap disable github-actions-v0.4
==> "github-actions-v0.4" is now disabled and will not be used for bootstrapping
$ spack bootstrap disable github-actions-v0.3
==> "github-actions-v0.2" is now disabled and will not be used for bootstrapping
