    In that particular computer lab, admin is *****, and paranoid one,
    too. He's more worried about security that functionality, and then you
    find suid bash in /tmp and learn that root password is name of the
    laboratory, with first character uppercased. Heh.

    BTW interesting things can be done with sak alone. (It is bye-bye
    vlock -a, right?). Changing console log-level and info-prints could
    lead to user seeing some info he's not allowed to see [perhaps part of
    some password are in the registers because they are now memcopied?],
    but I agree allowing that is probably okay.
