So, why does the depsolver suddenly start giving us generic-release instead of fedora-release? I'm not sure yet, but I have a theory - I believe fedora-release's dependency chain got longer, and that affects the depsolver's choice. In fedora-release-21-0.16, a requirement was added to fedora-release for 'system-release-product', which is provided by fedora-release-server, fedora-release-nonproduct etc. But 'generic-release' has no such matching requirement (nor do we in fact have a generic-release-server, generic-release-workstation, generic-release-nonproduct etc). So basically you get generic-release because it can satisfy the 'system-release' requirement with a shorter dep chain, because it doesn't also have to pull in a 'product' package to satisfy the 'system-release-product' dep.
The way this was working was that if you did an excludes in a kickstart file (such as -generic-*) the excluded packages were not available to satisfy dependencies. However this is a relatively recent change and maybe something undid it. In the past packages that absolutely were not to be available to satisfy dependencies were excluded on the repo commands.
And I think your analysis is spot-on. We haven't been keeping the generic-release-* stuff up to date (I think because it's maintained separately from the fedora-release-* stuff). Dennis, do you have any insight here? I know when we talked a few months ago, you were planning to try to bring these two upstreams together so we could avoid this sort of thing. Any word on that?
I tried to take a stab at this when we needed a generic-release update for F20 (there was a change in how provides were handled that required changing generic-release to allow it to be used) and there was no source for some of the included files. generic-release is now significantly different from fedora-release and I think it would be better if they had some common upstream.
