Before allowing mount access to someone, make sure that all your system
directories are opened by some process (so you can't mount over them).
Otherwise you may find somebody else's /etc mounted over your own (for
example), at which point nosuid is no longer effective (there are a number
of less obvious directories, depending on your system).
