The other problem is that the sysadmin is going to be in big trouble when I
come in the next day and discover that my latest development copy of qzt
(which is setuid uucp) has been blown away or un-permissioned....  Admitted,
group vectors are nice, but I'd need an infinitely sized group vector to cover
all the possibilities, so some things are still setuid instead of setgid.
