This works, with one major caveat: your first initial "init 6" or 
"reboot" may not work.  On the test box (where I could see the console), 
it "hung" at stopping the RAID monitoring.  Probably something to do 
with the fact the service wouldn't start without the proper /var, and so 
shutting down didn't happen smoothly.

So long as you're not too keen, and you *don't* log out straight after 
your init or reboot command, your shell is still alive.  A second 
"reboot" (not "init 6" in this case") fixes it and actually reboots
