Indeed. I had a nasty surprise when shutting down our OpenServer box a 
few days ago. As is my habit, I just typed 'halt'... and sure enough, 
the system halted. It was nice enough to flush the buffers on it's 
non-journalling filesystem first, but that was about it.

UNIX gives you enough rope...

Another good one on an OpenServer box is using 'killall'. Whoops. I now 
use 'pkill' all the time instead ;-)
