Yes. dnf has nothing like yum's rather complex set of heuristics for deciding this. https://bugzilla.redhat.com/show_bug.cgi?id=1183835 > If so, anaconda-installed and fedup-installed systems may end up > with different packages, which seems fairly undesirable. Well, they already do, for a couple of reasons; fedup doesn't do distro-sync, retired packages not being properly obsoleted, anaconda has never marked the groups it installs with yum's 'groups-as-objects' mechanism so upgrading doesn't add and remove group packages as it would if anaconda did. I haven't actually done it, but I suspect that if you installed, say, F19 Desktop then fedup'ed to F20 then fedup'ed to F21 Workstation you'd wind up with quite a different package set than doing a clean F21 Workstation install. > I suppose as long as fedup is part of the release criteria and get > tested there shouldn’t be huge surprises, but using the same > mechanism for all of (anaconda, fedup, post-install CLI, post- > install GUI) seems like the ideal we should be aiming for, not as an > aesthetics matter but as a “technical requirement” to minimize the > testing matrix (for both individual packagers and distribution-wide > QA). Agreed, reducing differences here as far as possible will always be a good thing (which is another reason I'd like fedup to do distro-sync). -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
