The directives in (gnu build install) specify files and directories that
should be created upfront when initializing a system—meaning when
running ‘guix system init’, or when populating a VM image.  The
boot/activation code assumes that these files already exist when the
system boots.

If we’re now creating /var/run in an activation snippet, then it no
longer needs to be here.

When doing such changes, I would suggest to at least run:

  make check-system TESTS=basic

to detect obvious mistakes, and perhaps run the “installed-os” test as
well (it’s much more expensive, so run it once you’re essentially done).

HTH!

Ludo’.
