There is a thread on the users' list * dealing with the issue that after an upgrade, there's no non-obscure way to clean cached metadata (or packages, even) from previous releases. The thread discussses DNF and Yum, but it may apply to PackageKit/Software as well; I'm not sure offhand.
It seems like we should handle this in some way on upgrade. My first thought was to make it an RFE dnf-plugin-system-upgrade. But, is that the right place? Maybe some time-base system should prune metadata associated with repositories for any earlier $releasever? (Or, actually, maybe for any repository which does not match a current configuration?) Or maybe a "dumb" process to sweep the cache based on age alone would do? * http://lists.fedoraproject.org/archives/list/us...@lists.fedoraproject.org/message/43OZYUTGFVZG6DTFKTJRHLUC7MET7LCB/ -- Matthew Miller <mat...@fedoraproject.org> Fedora Project Leader -- devel mailing list devel@lists.fedoraproject.org http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
