So as a RHEL, Gluster, and EPEL customer/user I have to say that I see
the benefit of it being in EPEL.  There is even a benefit to Red Hat
(first hit is free kinda thing) with Gluster staying in EPEL.  But
isn't there a technical solution to this. Is this what yum priorities
is all about?  Why doesn't the epel-release package require
yum-{,plugin}-priorities and set the priority of all EPEL repositories
lower than the standard one.  In theory the policy itself implements
this, but it doesn't negate the usefulness of backing up the policy
with config.

It also can provide a benefit for groups that may mirror some EPEL
packages to a local repository.   If the internal system ends up with
the local repository and EPEL attached (for various reasons I'm not
going to delve into) then the internal one would win because its
unlikely that anyone would set the priority lower than the EPEL by
default (although not beyond realm of possibility, but you can't save
