And for your further amusement, I got this message next, but I know where it comes from:

empeg:/etc# reboot
WARNING: could not determine runlevel - doing soft reboot
(it's better to use shutdown instead of reboot from the command line)
shutdown: warning: cannot open /var/run/shutdown.pid
You don't exist. Go away.
empeg:/etc#
