      Containers on disk consist of two parts: the layers of the image (which are read-only except when new images are pulled or removed), and the read-write top layers of the container. It is desirable to allow these two pieces to be placed on separate filesystems, allowing the images to be made entirely read-only to prevent external modification (among other advantages).

      This will require modification of the containers/storage library, and should be controlled by a new configuration option in `storage.conf`.
