Yes, that is one technique.

I would expect that it is the responsibility of the admin to create it,
where required. It depends whether the system is going to recieve "rogue"
ctrl-alt-del's.

The 3FS is handled by init. You can have it do whatever you like
(shutdown, send email, launch fireworks :)

  jon at pluto:~$ cat /etc/inittab | grep ctrlaltdel
  ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -h now

As usual, "man inittab" is your friend.
