Managind users for created containers

[chief93]

Hello
After few days I finally installed LWP on my Debian 8.3 (except cgroup features). It is very nice instrument! But I figured out that there are no options of managing users in created containers. Will be very cool and handly to add that kind of feature, because it is not comfortable to # lxc-attach -n ContainerName, passwd in it and then allow to log in by ssh.
And please, add .deb repo for installing and updates.
