+ gluster-users

IMO we should not put priority related stuff in gluster-release RPM.  I 
am for a wiki page to give work around for issues like these. As these 
are user decisions. As user should take decisons which repo should have 
priority and value of the priority if he chooses this solution.

As of now we are assuming that upstream (download.gluster.org) will have 
the right set of RPMs for users, but that might not be true. For e.g. in 
future if someone wants to move to CentOS SIG packages then it would 
need manual intervention.

I am not sure if we force yum to take packages from community repo i.e. 
download.gluster.org  then it is a clean solution . Because this brings 
some risk for packages which is built on glusterfs e.g. qemu  in RHEL 
base. It might break them. Either way something might break and it does 
not look like to be a clean and long term solution to me.

Also, I am against giving priority=1 to any repo. That actually makes it 
repo with highest priority which is IMO not necessary.  As repos without 
priority (which is usually the case) , have priority=99 as default. So 
any number less than that will give upstream repos higher priority [1].
