So, for the short term(relatively speaking), it seems that CentOS contributors wishing to push packages into EPEL would need to follow epel policy[1] for getting their packages pushed.
For some this is fine, as they're already contributing. For others, this is a duplicated workload with added stress.
I'd like to propose that we form a group of CentOS participants who are fedora/EPEL packagers to curate packages marked for sharing.
SIGs who have common packages to be shared would then be able to request that this group of curators submit the package via existing EPEL processes. This process assumes a couple things:
1. curators have access to modify the package in both systems (to correct things in spec files for example)
2. We adopt the fedora/EPEL packaging guidelines as much as possible to minimize changes required by the curators group.
3. We have some method of assigning package ownership to SIGs and to the curators.
Longer-term, I think we'll be able to work something out with EPEL that's a bit less manual, but I think this process should work for now.
Comments, questions, suggested changes before I propose this to the EPEL folks as well?
