URL redirect for centos stream does not work correctly

[thrix]

It would be great if this:

❯ curl https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podman-next/repo/centos-stream-$releasever/rhcontainerbot-podman-next-centos-stream-$releasever.repo
[copr:copr.fedorainfracloud.org:rhcontainerbot:podman-next]
name=Copr repo for podman-next owned by rhcontainerbot
baseurl=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/centos-stream-10-$basearch/
type=rpm-md
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/pubkey.gpg
repo_gpgcheck=0
enabled=1
enabled_metadata=1

Would return a generic copr repo with $releasever (as for Fedora):

❯ curl https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podman-next/repo/centos-stream-$releasever/rhcontainerbot-podman-next-centos-stream-$releasever.repo
[copr:copr.fedorainfracloud.org:rhcontainerbot:podman-next]
name=Copr repo for podman-next owned by rhcontainerbot
baseurl=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/centos-stream-$releasever-$basearch/
type=rpm-md
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/pubkey.gpg
repo_gpgcheck=0
enabled=1
enabled_metadata=1

@thrix, Can you please summarize the motivation and use case for why you need/want this? It will help us prioritize this issue.

[nikromen]

Patches are welcome for this!

[praiskup]

Ad ETA, we release like every few months, and this should be an easy fix somewhere here. If you want to be 100% we have this in a new release, patch would be helpful.

@xsuchy I need to use centos-stream copr repos from the podman-next copr on centos-stream envs and if I use generic centos-stream repos with $releasever in the URL, releasever resolves to 10. So, currently I can't mention a repo for c9s using releasever.

Sure, there are ugly workarounds, but rather have centos-stream urls behave the same way as fedora.

Hopefully fix is as simple as the linked frontend PR :)

The thing is, $releasever in the URL expands to an empty string, but that's still a valid repo URL, but the baseurl in it points to the first chroot in the list, so in this case centos-stream-10.
