This all has to be done with care or you end up with a system with some of the essential pkgs (kernel, glibc, yum, Python, ...) missing or in an endless loop.there are several thousand ways that I hate "removing already installed pkgs" as an automatic solution to a depsolving problem. That kind of thinking for me does not fill me with confidence as I've watched that behavior screw up far too often.We have implemented that in our own depsolver where it works quite well. We were able to upgrade between all Fedora releases since FC4 without manual interaction. But for a machine I care about I would omit the -y switch...In fact there is no way doing dist upgrades without removing old packages. And I have more confidence in an well thought algorithm than into a hand crafted pkg list.
some reasons why it actually does not work :( https://www.redhat.com/archives/fedora-devel-list/2007-October/msg01403.html eg. cyrus-imapd.x86_64 2.3.9-7.fc6 cyrus-imapd.x86_64 2.3.8-3.fc7 cyrus-imapd.x86_64 2.3.9-7.fc8 (2007-10-22) f7 < f6 = f8 sorry , the dist-upgarde can not work without removing packages but you should not patch yum you shoud patch the maintainers. -- shrek-m
