Both may be partially a packaging (spec file) issue, but neither problem exists with centos stream 8, so there are some differences in the distribution layouts/builds between the various clones. As always, those issues may be able to be worked around, but in my experience those clones are not always just a drop-in replacement, so some testing (probably a mass rebuild) would need to be performed just to be sure. Ultimately, the centos 8 support pivot in the middle of the lifecycle of el8 has just made things far more complicated than I believe most (and certainly I) wanted, and the resulting additional workloads that has imposed on Nicolas and colleagues are certainly an unexpected (and likely un-resourced) support burden. (*) When I have some free time to look at the root causes, and they are indeed bugs in the distros (rather than my own packaging issue) I'll open bugs in their trackers, but since centos stream 8 works, I have not been especially motivated to this point. And then there is the ability to get a (free) redhat subscription for at least some use cases (although I have no idea whether that free subscription can be used for the rpmfusion koji builders).
