You need to do the same thing with yum-priorities as well ... basically, yum-protectbase and yum-priorities are the same thing, with protectbase having 2 priority groups (1 and 0) with priorities has 99 priority groups (99 down to 1). I would use yum-priorities and not yum-protectbase.
In both cases, you are not going to be told about packages already
installed that are newer than those in the CentOS.
You can find those RPMs though by doing this:
rpm -qa | egrep "\.rf" | sort
that will tell you all repoforge rpms installed ... then do this to see
which ones also have duplicates from base or updates:
yum --disablerepo=\* --enablerepo=base --enablerepo=updates
--showduplicates list all $(rpm -q --qf '%{name} ' $(rpm -qa | grep "\.rf"))
That should work to tell you which .rf packages are also in base or
updates.
