Description of problem:
Running "yum remove <pkg>" doesn't clean up the dependencies for <pkg>.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Ensure xemacs not installed.
2. yum -y install xemacs
This installs the following packages, due to xemacs dependencies:
3. yum remove xemacs
The xemacs package is removed. However, the following packages are not removed,
even though clearly they are not required by any other package on the system:
I would have expected all the packages that xemacs depends on, and which are not
required by other packages, to be removed.
yum remove <pkg> does remove all things that depend on package, but not vice
versa as there's no real way to know that nothing else on the system (including
things built or installed by hand) don't depend on them.
If you install the yum-utils package, there is a utility called package-cleanup
which can help you to find leaf node packages and remove them.
