In short, you need to query the SRPM & RPM dependencies and their runtime and build time dependencies, recursively. You also need to do that on every architecture (due to the potential use of conditional build deps), so your process should involve SRPM rebuilds as the ones you download from Fedora repos have only been built on one; and it's random -- there's a chance you won't be able to resolve your tree if you use those. Binary RPMs are already available for all arches so you just need to fetch the repodata. You can do all this on a single host and arch, don't worry. No uploads and actual RPM builds are necessary. Once you have your package list, just compare it to your target distribution's package list and you have your set. It's no longer maintained and it was rather quirky buy could try depchase; it did exactly this when we were experimenting with fully modular distributions: https://github.com/fedora-modularity/depchase P _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
