Hey, I just wrote a script using the yum modules to check to see if a set of repositories have dependency closure for all packages in the repositories. it's very simple and obvious but it has some nice results: I ran: cutter:~$ python ./repoclosure.py development Not running a root, might not be able to import all of cache Reading in repository metadata - please wait.... Checking Dependencies Repos looked at: 1 development Num Packages in Repos: 2663 package: openoffice.org - 1.1.3-2.7.i386 from development unresolved deps: libedataserver.so.3 libebook.so.8 package: gnome-python2-nautilus - 2.6.0-5.i386 from development unresolved deps: libnautilus.so.2 package: struts11-webapps-tomcat5 - 1.1-1jpp_2fc.noarch from development unresolved deps: tomcat5 package: nautilus-media - 0.8.1-4.i386 from development unresolved deps: libnautilus.so.2 package: evolution-connector - 2.0.3-1.i386 from development unresolved deps: libcamel.so.0 libedata-book.so.1 libedata-cal.so.5 libedataserver.so.3 libgal-a11y-2.2.so.1 libgal-2.2.so.1 libebook.so.8 libecal.so.6 so that's kinda cool b/c now we know what packages simply aren't going to resolve out in development right now if you tried to install or update to them. http://linux.duke.edu/yum/download/misc/repoclosure.py I think it works okay, it seems to at least :) You run it like: repoclosure.py repoid repoid repoid or if you want it to check your default repositories that you have enabled in your yum configuration then just run: repoclosure.py You need to have yum 2.1.13 installed to really test it. The only other thing you might want to do is either: 1. run repoclosure.py as root 2. run yum makecache as root with the repositories you want to use enabled. thanks, -sv
