Along similar lines, if we're looking at frequent admin errors: I've noticed 
an increasing number of people using "reboot" rather than "shutdown -r NOW" on 
the basis that on Linux (and perhaps other systems), reboot gives a clean 
application shutdown.  I wonder if we should be making a similar change -- a 
lot of people may be risky data corruption/loss due to unclean application 
shutdown as a result of that misunderstanding.
