Hi,
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.
