It seems pirut has been replaced by PackageKit.
That would not be an issue unless:
1) it does not show the packages in groups. if I don't know the package
name, I'm lost
2) I've added some other repositories under /etc/yum.repos.d for ppc64
(I'm running on a PS3).
They are disbaled, and when I ask for the Software Sources in
gpk-application they are not enabled (which is correct).
The problem is that when I search for a package with a given name, I get
a lot of packages from both ppc and ppc64 (which is wrong).
yum works properly with those extra repositories, and it ignores them
unless I tell him otherwise.
