When I took over running a labful of SunOS machines that were used by our
CS students, one of the first thing I did was turn off a few things in the
system call vector for UIDs higher than a "staff" cutoff. That included
things like chown, chmod and setting the umask. As well as making it
harder for them to share solutions, it also had the advantage of making
other systems more tempting targets...
