Using `--from` to set the target releasever doesn't work yet because we
_need_ to set the `releasever` field since the repo files reference it.
There's a pending rpm-ostree PR to fix this but for now hack around it
by manually injecting the necessary variables in the treefile.
As agreed in https://gitlab.com/fedora/bootc/tracker/-/issues/39, we're
going to be maintaining the treefile for all Fedora versions in the
`main` branch. Accordingly stop hardcoding releasevers and repos in
the treefiles.
But for now, we're still building the official image in pungi using the
non-container-native path, so add compatibility stubs to not break it.
Coincidentally, this doubles down on the proposed API to build the base
images for different Fedora versions using the `--from` switch. Document
this in the README. But note this doesn't work yet because nothing is
telling rpm-ostree which repos to use or what the releasever should be.
We want tier-1 to be another consumer of tier-x, kind of like its own
top-level Fedora variant. That way, tier-1 is now a strict superset of
tier-x, just like the other variants.
- Make very clear that tier-1 is the default image
- Link to our issue tracker for supportable base image customization
- Note use of `--build-arg=MANIFEST`.
etc.
