There is a suggestion in the kernel sources that a chrooted process should only
be able to see processes that have the same root or that have a more restricted
root.

The comment is in the source for fs/proc/inode.c:
http://lxr.linux.no/source/fs/proc/inode.c?v=2.3.3#L161

169 * XXX TODO: use the dentry mechanism to make off-limits procs simply
170 * invisible rather than denied? Does each namespace root get its own
171 * dentry tree?

I wondered if anyone has done this, and wheter there are plans to include
this in the main source tree.

Regards
Peri Hankey
