>Description:
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.
>How-To-Repeat:
>Fix:
no bug, no fix! I added/modfied few lines to implement the feature.
I patched it from /usr/src/sys.
Best regards
Oliver
