ObDisclaimers: I have no idea what, if anything, I just broke.
I have modified /etc/inittab and /etc/kbd/default.map.gz. In
/etc/kbd/default.map.gz, I have Control-Alt-Insert mapped to
KeyboardSignal, and in /etc/inittab, I have added a line (okay, I
uncommented one that was already there and modified it) that runs
"shutdown -h now" when it receives a kbsignal. This way, when I press
Control-Alt-Insert, it does something almost like Ctrl-Alt-Del, but
halts instead of rebooting. On my laptop, or on some machines which
support power management, this turns off the power as well. I suppose
you could modify the Ctrl-Alt-Del sequence to halt instead of
rebooting, but I like the option to choose rebooting or halting.
I can provide copies of the relevant parts of those files on request - I
have three machines running Debian right now, and I've made this
modification on two of them. Guess which of the three has net access
:-)
