Generally speaking, we add epel with specific packages to ovirt-release*.rpm,
and do not support all of epel. In practice, the only problem I personally
know of is with epel packages that also exist in other ovirt-release* repos,
perhaps in different versions.

A recent example we bumped into:

https://gerrit.ovirt.org/71386

ovirt-live uses its own set of repos, and used all of epel, and epel has
a newer version of collectd than in the opstools repo (which is what we
use). But it doesn't have collectd-write_http. So jenkins failed:

Perhaps add them with includepkgs, to be on the safe side, and not
all of epel.

Best,
