Comment 5 for bug 1437054

Please review the following patch whenever possible. This should ensure that the lxc module has the ability to randomly generate passwords on all containers built with all lxc container templates provided by the default lxc packages.

This also creates an additional task entry in the `lxc-container-create` role to randomly generate a password for the {{ lxc_container_user }} on every lxc-container-create run and provides a tag to be used to regen a password for the {{ lxc_container_user }} if the regeneration is needed/required to be run as an individual task.
