This patchset allows to build Discoverable Disk Image(DDI)s, like
systemd-sysext
systemd-portable
systemd-confext

In the current implementation the images are not stripped so
 especially sysext contain a full copy of /usr and /opt.

This patchset uses systemd-repart instead of wic as it is
easier to describe interdepended partiton layout as required
by DDIs.


Quirin Gylstorff (3):
  Add Discoverable Disk Image definitions to ISAR
  Add imagetype Discoverable Disk Image(DDI)
  classes/image: Add DDI imagetype

...and that will allow... ? Would be good to draft the use case here as
well.
