Also, this provides a nice, clean, portable way to require
the root password to interrupt the boot (by marking console
insecure) while allowing root to log in once the system is up
and running (because the getty runs on constty, which is marked
secure).  To do this before, you used to have to name the
specific underlying tty device -- which could change if system
configuration changed, even on the same port.
