Waiting for a reboot's firmware phase to power off is impractical,
even if the box is next to you.

Using "sudo shutdown ..." whether you're logged in via a (local)
console, a remote console, or an ssh session is simpler and more
consistent.

Furthermore, ctrl-alt-del only works if you're physically at the
console or, via the esc-R_esc-r_esc-R sequence, if you're using
out-of-band management (and the latter doesn't always work).
