Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
It simply creates a test user and tries to create and start a container as that user. Tries to lxc-attach to that container to test network connectivity. Signed-off-by: Serge Hallyn <serge.hallyn@ubuntu.com> Acked-by: Stéphane Graber <stgraber@ubuntu.com>
