        You have to login as root to shutdown the system. You don't
        want to 'just turn it off' since you can loose data.


Know before you do this that shutting down the system rather than just
throwing the scram switch can cost you.  If a system is known to be cracked
then you must assume that _everything_ on the machine is compromised.
login could be replaced with a program that mails your password somewhere.
init could be replaced with a program that does whatever.  Logging in as root
to shutdown puts you at risk of further damage.
