Did anybody tried the example with the mount namespaces ?

I tried it both on Fedora 18 and Ubuntu 12.10 and it did not
work.
For Fedora 18, it could be because of the shared flags.
(running cat /proc/$$/mountinfo show shared).

But for ubuntu:
cat /proc/$$/mountinfo |grep shared
gives nothing.

I would appreciate if someone that tested it and it worked
will post which OS and which kernel he uses.

Anything that ships with XFS enabled (pretty much any distro) can't support user namespaces yet since XFS won't work with them. You're probably stuck compiling your own for now (which is what I did and then tossed it into a VM).
