I have a little thing I add to some of the Slackware servers I set up that would fit right here.  Many times when I setup a server for a small business, the people want to shut it down on the weekends or at night, etc. and so rather then expecting these non-computer people to first login and then shutdown, instead of just turning off the power, I edit inittab to include this:<br />
 <br />
 # What to do at the &quot;Three Finger Salute&quot;.<br />
 ca::ctrlaltdel:/sbin/poweroff -h<br />
 <br />
Now I just put a message on the keyboard &amp; screen to &quot;Press Ctrl Alt<br />
Delete to power down.&quot;  My slack boxes power down gracefully and no one<br />
even has to login.  Best of all it is quick and easy for the person who has a tendency to just turn stuff off.
