That's totally fine!

I don't think that it makes sense to ship the user-space packages in
EPEL if the kernel functionality isn't present in RHEL. This was
something that we went over in Hyperscale with btrfs-progs, and my
argument has basically been "people expect EPEL stuff to just work out
of the box on RHEL, and we can't offer that with btrfs-progs in EPEL",
so now Hyperscale maintains btrfs-progs in CBS. I suspect the same
tack will make sense for this too.

It might make sense to see if we can bring ELRepo into the fold. A
requirement for that would be the ability to build with RHEL in the
buildroot, though. Perhaps we can get an arrangement for CBS to have
RHEL buildroots like EPEL has?
