[lxc-users] lxc user-space start error

[Nilesh B.]

After some troubleshooting, now I can start container (with following
message) and able to run sudo inside container

p1 login: <4>init: setvtrgb main process (569) terminated with status 1
 * Stopping save kernel messages   ...done.
<4>init: plymouth-upstart-bridge main process ended, respawning

and output from /proc/self/mountinfo is:
