Using my early-gdm scripts, X and gdm are already running their
sockets from a tmpfs.  It would be trivial to reverse what I do on
bootup for shutdown and unmount everything from underneath X and gdm.
When the machine completely shutsdown *poof* tmpfs is gone and there
are no ugly sockets or temp files left to cleanup on boot.

I have been playing with this on the side to allow filesystems to do
their maintenance fsck's on shutdown instead of bootup.  This gives
you more control over whether you have the time to wait on the
maintenance or not.
