I realy would like to have this, but keep in mind that not every port has
this Ctrl-Alt-Del thing as a key combination. On my sparc64 it is delivered
as a dedicated interrupt from the main PCI bridge (the power button on the
chasis, that is - I didn't yet test the power key on the keyboard, as I don't
have one attached normally).
This has been discussed about a year ago, when I suggested to make "some part
in the kernel" (whatever that is, i.e. keyboard driver or something else)
schedule a SIGPWR to process 1.

I would prefere if there would be a query on the console (with short timeout),
or, if you are running X an X applet popping up asking what to do (shutdown,
reboot, cancel) - with a short timeout too.
Later we could add "suspend" to this, for ports that support it.
IIRC this is what Solaris does do now.
