You can make init respond to the KeyboardSignal that is generated by pressing a particular key combination. On my RH9 system the KeyboardSignal is generated by pressing Alt+Up by default. It's a good idea to disable this key combination from generating the KeyboardSignal because it is possible to press Alt+Up accidentally when you mean to press Alt+Right or Alt+Left to swich to the next or previous console.

To change the key combination used for to generate the KeyboardSignal I edited the file /lib/kbd/keymaps/i386/include/ to disassociate Alt+Up from the KeyboardSignal. I found the line:

alt keycode 103 = KeyboardSignal

I changed it to:

#alt keycode 103 = KeyboardSignal

I decided to assign Ctrl+AltGr+End to KeyboardSignal. To do this I added the following lines to the file /lib/kbd/keymaps/i386/include/

# Assign Ctrl+AltGr+End to KeyboardSignal
control altgr keycode 107 = KeyboardSignal

You may find out what keycode is associated with a key by using the showkey command.

To get init to perform a command when you generate the KeyboardSignal I added the following line to /etc/inittab:

kb::kbrequest:/sbin/shutdown -t3 -h now

Now it is just a matter of running

# service keytable restart
# telinit q

I found that after running those two commands that the KeyboardSignal is associated with both Alt+Up and Ctrl+AltGr+End. This will change next time you reboot. Just try to avoid pressing Alt+Up in a console accidentally until then.

EDIT: I have actually found now that after running "service keytable restart" that Alt+Up actually is disassociated with the KeyboardSignal.
