In the past, I have attempted to build RHEL8 RPMs on RHEL8. That is a fool's errand! I realize that now, because RHEL is not self-hosting.
(I have loads of test RHEL & OL 7 & 8 servers available, no Fedora.)
So I have to stand up a Fedora server to build the RHEL 8 RPMs. Currently, Fedora is at Fedora 35 and RHEL8 is based on Fed 28. Is that ok, or do I have to find Fed 28?
I've reviewed the RHEL9 beta (which is based on Fed 35). Doesn't seem that different than RHEL8.
