This is a genuine bug, but I'm not convinced it is the whole fix.
What about non-systemd images?  /run is meant to be a tmpfs, which is
why udev installs a volatile link from /run to /var/run.  If we create
a directory in sysvinit cases, we'll also need to mount a tmpfs on it.

The FHS 3 draft specification actually ratifies /run[1] so we could
take this advantage to start cleaning up our volatile layout in /var.
Start by always creating /run in base-files, and always mounting it as
tmpfs in fstab for the non-systemd case.  Then we can symlink /var/run
to /run, /var/lock to /run/lock, and so on.
