/var/run depends on /var, which is allowed to be a separate filesystem, and
therefore not available during all portions of the boot process or shutdown.

Having a single /run available before, during, and post-boot allows for
a much cleaner implementation. Applications can still use /var/run and
have their paths work, of course.
