Mock currently makes a cached copy of the buildroot it just created so it doesn't have to redepsolve and download/install the rpms each time. So the first time you run it makes a cache. You aren't clearing out the cache each time, are you? That would definitely eat up a lot of time. -sv -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
