Fedora (well, Yum, but Fedora uses Yum) have a useful little util called package-cleanup that looks at dependencies and tells you which RPMs aren’t a dependency of any other RPMs. The idea is that you can find which RPMs are installed and don’t need to be (because you no longer have the app you installed them for). So far I’ve not found anything similar in Suse/Yast.
Is there a simple way to do an equivalent to “package-cleanup --leaves” in Suse to find unused library RPMs?
Someone has asked a year and a bit ago, but they never seem to have got an answer (well, someone said “Yast can do it” but preceded it with “unfortunately”, which implies a missing “'t” from “can”).
