well, let me just say this about that:)
I used to shut down a UNIX system in 5 seconds flat. The way I did it was:
# while true
do
sync
uadmin 2 0
done
CLICK ( machine shuts itself off)
that command dropped an AT&T unix box to its knees in 2 seconds. SO it was a
real good idea to run the sync command FIRST.
