systemd-sysext can load a raw-image containing usr/ and opt/ folders to mount them as RO overlay over the rootfs, to "extend" the systems. This class provides the necessary changes/additions to the enclosed filesystem so that systemd-sysext accepts the extension for "merge" into the rootfs. With such a created image, placed into the correct folder (see [1]), `systemd-sysext list` should be able to list the "extension" and `systemd-sysext merge` should enable the overlay. On both commands a preceding "SYSTEMD_LOG_LEVEL=debug" can aide in figuring out what is amiss.
