Do these actually need to be excluded now? I think that with recent yum (which we end up depending on anyway), if you have a package set which includes

    fedora-release
    generic-release

and then you explicitly specify to install 'generic-release', provides which generic-release can do will get used "first" and then we'd only fall back to fedora-release if there was a provide which couldn't be satisfied.
Well, upd-instroot selects "system-release" and "system-logos", and let's YUM figure out whatever is the best match. The user (or application triggering buildinstall) is not able to select the brand packages.

You're switching the use of system-release and system-logos to be
$brandpkgname-release and -logos, though.  I don't see anything left
referring to the system-logos and system-release package.  So with the
explicit calling out of a brandpkgname, I'm not sure why we need both
that *and* the excludes


I'm not sure if I understand your concern correctly but I'll try and answer anyway;

Anaconda doesn't need to use system-logos/system-release to select the package being pulled in for <brand>-release and <brand>-logos, and that's not what they were intended for either, if you think of it.

The system-release and system-logos Provides: have been added so that other packages could have something to require other then requiring a specific brand package, and not the way we're using them now; selecting the brand package using a couple of workaround such as |grep -v generic-logos and the |head -1

The system-release and system-logos Provides that every brand package has though still helps in resolving the dependencies (and borking if they can't be met).

Anyway, this is the alternative of a patch sent earlier, with the --logopkg option to buildinstall. If we like that better (and in fact I do because it is more flexible to the user/program), I can rebase that and submit it?

Kind regards,
