Spack is designed to run out of a user home directory, and on many
systems the home directory is a (slow) network filesystem. On most systems,
building in a temporary filesystem results in faster builds than building
systems the home directory is a (slow) network file system. On most systems,
building in a temporary file system results in faster builds than building
in the home directory. Usually, there is also more space available in
the temporary location than in the home directory. So, Spack tries to
create build stages in temporary space.

When set to ``true``, concurrent instances of Spack will use locks to
avoid modifying the install tree, database file, etc. If false, Spack
will disable all locking, but you must **not** run concurrent instances
of Spack. For filesystems that don't support locking, you should set

enabling locks.

When enabled, Spack will look inside your ``PATH`` for a ``ccache``
executable and stop if it is not found. Some systems come with
``ccache``, but it can also be installed using ``spack install
ccache``. ``ccache`` comes with reasonable defaults for cache size
and location. (See the *Configuration settings* secion of ``man
ccache`` to learn more about the default settings and how change
them.) Please note that we currently disable ccache's ``hash_dir``
and location. (See the *Configuration settings* section of ``man
ccache`` to learn more about the default settings and how to change
them). Please note that we currently disable ccache's ``hash_dir``
feature to avoid an issue with the stage directory (see
