Halt is maybe nice on headless machines. You should already be able to do this using the "kbdcontrol" command to change the mapping of ctl-alt-del. You should be able to do this by changeing "boot" to "pdwn" in the keymap file kbdcontrol -d | sed -e s/boot/pdwn/g > mykeymap kbdcontrol -l mykeymap You could then get this new map loaded at boot time by putting it in /usr/share/syscons/keymaps and putting: keymap="mykeymap" in /etc/rc.conf. You can get more details about keymaps with "man kbdcontrol" and "man 5 kdbmap". David. State Changed From-To: open->feedback Is using kbdcontrol to change the mapping an acceptible solution for you?

I wrote a few lines with two new kernel options. My Desktop machine now turns power off after pressing ctrl-alt-del. Nice feature "from" Linux, where it is solved some dirty outside the kernel with /etc/inittab imo. Halt is maybe nice on headless machines. Fix: no bug, no fix! I added/modfied few lines to implement the feature. I patched it from /usr/src/sys.
