To be perfectly honest, the differences between EPEL and Base+extras can usually be completely ignored anyway. While somethings may be in epel and extras .. and the extras versions might lag, the extras version likely came from EPEL in the first place and was added as a build requirement for some other package in extras. This means that if there is a newer version in EPEL later, it is likely not going to cause a problem if it is installed on CentOS .. and in reality, we should probably be pulling that newer EPEL package into extras anyway. I don't think, if you stay in the elrepo, EPEL, and Base+Extras family that you are going to be hurt very often using whatever yum finds without yum-priorities at all. I would add the NUX repo to those as well. If you go outside those 4, maybe yum-priorities become more important. I am sure with 8,000 or so total packages, one might find a conflict that matters .. but I don't know of any that matter right now. By matter, I mean that there is an actual issue using the newer package from the 4 repos, whichever one that is.
