libsolv can generate special solvables when packages are tagged correctly, which could be exposed through the DNF API such that dnfdaemon can identify it as a "group" type and represent them specially. This is how patterns work in (open)SUSE with Zypper. But actually, I'd rather not go to that, because the composition groups based categorization is too weak and incomplete when it comes to sorting packages for people to browse (which is what dnfdragora does). This is why I'd advocate for the return of the RPM Group tag, because it's a useful way to categorize the entire collection of packages. But if we insist on comps-style grouping *only*, then we could do that with metapackages. We can also do it to some extent with AppStream data, but again, that's incomplete from the perspective of the distribution as a whole. It's not useful enough for a package manager view, though it's certainly good for an app-centric view. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
