Comment 3 for bug 924281

If someone encounters these symptoms in Precise, the more detailed instructions to fix it is to adjust apparmor as described in http://www.stgraber.org/2012/05/04/lxc-in-ubuntu-12-04-lts/ , in the section labeled "Container nesting." The apparmor change is part of Quantal, so the blog post's steps should no longer be necessary after Precise.
