But ultimately removing rpm transactions is an optimisation to rpm which, when it lands, the compose plus numerous other compoents that use that code path will just consume and at that point get the benefits of, it's not a reason to skip a release nor is it going to be a revolution that gets the composes down to an hour. I don't believe that that alone is and order of magnitude change, do you have any actual hard figured to back the statement up? _______________________________________________ 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
