The union mount could *very* interesting for the containers (aka
namespaces). If you create a container, you can share the same rootfs
between the different containers and make a COW for each container
writing on its own filesystem, no ? Using together the mount namespaces,
the union mount and the ro bind mount, can be very powerful IMHO.
