shouldn't it also be possible to freeze the container for full clones? that prevents modifications to the container file systems  by the container, so we can safely copy everything to the clone and then unfreeze the original container again. it would even be possible to use the same two-step rsync mechanism from suspend backups to minimize downtime.. for  containers where freeze is problematic (i.e., the explicitly not recommended "FUSE in container" setups) the full clones without freezing are still possible by simply shutting down the container.
