I've handed out a patch to solve this problem in a different way:
instead of setting up a different key for *every* kind of reboot, mine
tries to make it easy to change (at compile time; being able to do it
later would provide too much opportunity for confusion) the signal that
gets generated by ctrl-alt-delete.
I'm not sure which approach is better. Mr. Malone's is certainly a lot
more flexible than mine in the sense of not changing what ctrl-alt-
delete already does. However, flexibility may not be an advantage in
this case; you don't want too many magic keyboard combinations bringing
the machine down. Furthermore, my patch is *more* flexible in the sense
that it lets you attach *any* signal to the ctrl-alt-delete key combo.
This is useful because most of the requests I'd seen were actually for
powerdown, rather than just halt, to replace reboot.
Anyway, my patch is at the bottom of this message. I've never submitted
it in a PR, because I've never gotten around to testing it myself (I
don't reboot, except as part of system upgrades...) and none of the
people I've given it to have given me the (promised, in some cases)
feedback on it. But I figured I should toss it in the mix if it might
get obsoleted by other changes.
Be well.
