For the correct order, "shutdown -r" calls reboot which calls init which
calls rc.shutdown.

Doing a shutdown -r is the same as a reboot without the warning to logged in
users and shutdown handles the logging instead of reboot.

shutdown also give operator more possibilities than a clean shutdown some
which could be very bad.
