They're very helpful when reading the test job in LAVA. I can add a comment explaining why they're there but I'd like to keep them.
Static delta is a variant of OTA update test. It exercises a feature of ostree that lets limit the number of downloads from ostree server by packing the objects into compressed packages. ostree server is also able to calculate the size of the whole update. This allows aktualizr-lite to reject the OTA update if it's size exceeds the threshold limits. Default threshold in aktualizr-lite is 90% disk occupancy after OTA update.
