I'm not sure I agree with this approach -- perhaps root processes should
not be allowed to use the mount() syscall if root_dir != real_root. The
other main source of nastiness is ptrace() -- this needs to be banned in a
similar manner. There are other ways root could escape a chroot()
jail, we need to think about them and eliminate them one by one.
