The plugin could require yum >= 3.2.25, and then do something like (in config or prereposetup): for repo in repos: repo.mdpolicy.append('prestodelta') ...which would auto download presto MD when yum gets new repomd/primary. People might complain though :) ... another kind of fix would be for the plugin to call ".cleanExpireCache()" if the MD fails to download. The nice server side fix is to keep around more than one complete set of MD (possible now we have unique MD filenames), so there would have to be two updates within the client side cache timeout. But I'm not sure how easy that is. -- James Antill - james@xxxxxxxxxxxxxxxxx http://yum.baseurl.org/wiki/releases http://yum.baseurl.org/wiki/whatsnew/3.2.26 http://yum.baseurl.org/wiki/YumMultipleMachineCaching -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
