Well changing the line in /etc/inittab so that ctl-alt-del does shutdown
-h (halt) rather than shutdown -r (reboot) is quite handy. It saves
having to hit the off switch just before the re-boot gets started. This
way the system shuts down and waits, for you to either switch the box
off or do another ctl-alt-del which starts a reboot (I just found that
out by accident, must be something in the BIOS!) Thing is, ctl-alt-del
don't work from a graphical terminal, you have first to do a
ctl-alt-F1|F2|F3|... to change to a text terminal, so a shutdown button
would still be nice.

This SUID business is what I don't understand. I want to write a script
that can be called by any user and which itself executes /sbin/shutdown
-h which only works for root. What exactly do I have to do for this to
work?
