[lxc-users] Problem starting trusty container on 16.04

[Mike Bernson]

I have create a 16.04 container on 16.04 as unprivileged container and it works.

I then tried to create 14.04 container on 16.04 as unprivileged container and it does not get
to the login prompt.

If create 14.04 container privileged and start it that works.

I have done everything as root.
