# Setup /run if not already in use. Note that the intent here is to
# make the existing /var/run and /var/lock available as /run,
# /run/lock, respectively. When the system is next restarted, a
# proper /run tmpfs will be set up. The bind mounts set up here are
# intended to recreate the directory hierarchy using the existing
# locations in order that packages may transition to using /run
# without a system restart.
#
# If in a chroot or vserver environment (i.e. a guest, which does not
# run rcS scripts), do not do any messing around with mounts, and
# don't migrate /var/run, /var/lock or /dev/shm. Bind mounting would
# not work in a chroot, because the migration would only be
# temporary--the rcS scripts are not guaranteed to run, so we must do
# the migration by hand at this point. We create symlinks from the
# new locations to the old locations, which should be safe. The
# sysadmin should, if they care, move the old locations to the new
# locations and create compatibilty symlinks at their convenience
# following the upgrade.
# chroot upgrade scenarios (from vorlon):
#
# - /dev is not bind mounted. sysvshm should be mounted *somewhere*
# within the chroot, but we don't know where this will be done and
# we're not going to do it ourselves. So dictate that this should be
# /run/shm, and make /dev/shm a symlink there.
#
# - /dev is bind mounted, and /dev/shm is a symlink to /run/shm
# (because the parent environment is also a recent Debian/Ubuntu
# release). Make the /run/shm directory.
#
# - /dev is bind mounted, and /dev/shm is also bind mounted. This is
# not a good situation to be in, because it means that the future
# correctness of the chroot is dependent on the setup remaining the
# same on the host system - which it won't if the host system is an
# older Debian/Ubuntu release that is later upgraded. But we do the
# best we can for now, and make /run/shm a symlink to /dev/shm.
#
# - /dev/ is bind mounted, and /dev/shm is a non-bind-mounted
# directory. We can't fix this, so we should just create the
# /run/shm directory and leave /dev/shm alone.
