Can one of the admins verify this patch?

I do think we'll need to keep building the libs for EL7 so it'll need to be a bit more complicated, but let's see what the build process shows

Our CI requires a change in release and accompanying changelog entry. If you add those, our build system should run and we can see the results.

@evgeni I'd like your thoughts on this.

We need the libs part on EL7 tho, as that comes with an ancient createrepo_c.
And we might get ahead of RHEL at some point (again) where we need a createrepo_c 0.18, which RHEL doesn't have yet.

But in general, yes, this is how we should do it ;)

Probably obsolete, now that pulp_rpm needs a newer createrepo than available in CentOS 8 anyways:
