Why doesn EPEL use repotags?
There were a lot of long discussions in the months of EPEL about using repotags or not. Lots of people from inside and outside of Fedora and EPEL as well as maintainers from other repositories participated in those discussions. No real agreement could be found if the benefits outweigh the disadvantages — part of the problem was that people sometimes not even could agree what benefits or a disadvantages repotags have (or if there are any). The final decision in three voting’s (one done by FESCo before EPEL had a Steering Committee and twice done by EPEL’s first Steering Committee) was to go without repotags in EPEL.
