Wait, that sounds way too stable. We need to find a more unstable
approach! ;) Well, Docker is only just gaining SELinux integration, so
you're even a step ahead. :)

Well, I was more thinking of having these two options:
- Create image using ImageFactory (and initialize ostree in %post)
- Copy the already built base image and initialize the ostree within
(for which there should be several possibilities)
But good to know you can create qcow2 disks directly. But hardcoded
stuff doesn't work for our needs. Even if the code would match our
exact needs, they are just as much in flux as everything in the cloud

Kindly let us know once it's there and usable. I don't expect it all
too soon, though. Anaconda is a rather complicated matter.
