BTW, if the user is logged in /dev/console, the system is (high probably)
in single user (maintenance) mode, which implies: a) those user _is_
the system admin or b) the sysadm is so foolish to leave the system open to
people in single user mode (aka System maintenance mode).
In any case is _their_ fault if he later has his head screwed on with the
big trouble of re-install the console device in order to be capable of
boot the system.


Cheers,
Peter.
