It could be something similar to Fedora ELN, where a subset of the main repo that might be useful on old hardware can be rebuilt (though unlike ELN, I suggest that this should be an entirely separate infrastructure not maintained by the Fedora Project). Such a project could then live or die based on willingness to maintain it and stop holding back Fedora as a whole. -- _______________________________________________ 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 Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
