    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.
