Hello,
we are moving forward with the idea of distributing PXE files via OCI registries. We have filed a Fedora Change and we have a working testing pipeline for distributing the files:
https://fedoraproject.org/wiki/Changes/KickstartOciArtifacts
The artifacts are extracted and pushed via buildah tool, there is still no download artifact support in podman but upstream is discussing the idea. In the meantime, tool from Fedora named golang-oras can be used to download artifacts:
$ oras pull quay.io/pulp/fedora-kickstart-artifacts:40-amd64

The namespace is temporary, we will move the repo into pulp project for the time being and hopefully the change is accepted and the final artifacts will be pushed in the official fedora namespace.
We want to do a followup for RHEL and CentOS Stream. Once Fedora Change is accepted and the pipeline is final, including signing with GPG keys, I will update the Foreman repo doing the same thing for non-RH OSes.
Cheers!
