Opensuse doesn’t have rpm-ostree. Their immutable offerings are just snapper/btrfs snapshots before changes to the system.

Such a setup is nowhere near as powerful. rpm-ostree can rebase itself based off of a container/oci image. It can layer images on top of eachother. Rather than just tracking when changes happened, it can also track what change happened, in a git style setup.

Why would it? OpenSUSE isn’t a good choice for a base system it is fairly obscure and the base is rather large.
