This sounds good.

Preferably it's the aboot minimal aarch64 rpm-ostree qcow2 we test build. It's the one with the most uniqueness to other rpm-ostree OSes.

If nobody going to take it, I can take it as I recently looked into the build scripts for rpms. My guess probably the work would be similar to the initoverlayfs, copy .packit here and adjust it. @Yarboa make sense?

[ericcurtin]

By the way we need to run an osbuild to do this... It's gonna be different to the existing initoverlayfs build...

You need to have the newly built rpm-ostree rpm as part of the AutoSD image building process to test this...

In production we don't use many rpm-ostree features at all during runtime, it's mainly called during osbuild, so we have to do this with the new rpm-ostree rpm essentially:
