Hi Robert, yes, I've just noticed this project a week or so ago.
While I have your attention, probably too late now, I wonder was Oz ever considered for
disk-image-building? (I've read the README of diskimage-builder briefly)
Oz has been in development (& has an amicable upstream) for a couple of years, building
JEOS (just enough OS) targeting multiple operating systems including Windows. It's not too
RPM specific either. There's Debian packaging notes:
All apologies if this discussion happened elsewhere, please point me to it.

(Or other similar use cases).
Understood. Thanks for bringing it up.
