I want to correct one thing: EPEL is not an Enterprise repository. It
is a nearly complete volunteer effort and things will add and
disappear over time as volunteers come in and out. We try to make it
stable and useful but we do not guarantee/promise/etc any Enterprise
level 'support'. If you are needing that then I would contract out for
it with someone who can do that kind of work... or come up with
techniques to mitigate changes that will occur in EPEL.
