Docker is a superset of lxc.
Not anymore.
Although it still supports lxc, docker now defaults to libcontainer (https://github.com/dotcloud/docker/tree/master/pkg/libcontai...), it's own container implementation.
But it behaves differently. For example, if you shut down a Docker container, changes are not saved.
That's not true, and it has got nothing to do with the pause/unpause feature. You can see stopped containers with `docker ps -a`, and you can restart them.
In Docker 1.0 you can now use docker pause/unpause.
