With EOL of RHEL 7 and EPEL 7 we recently got several questions how long we will keep epel-7-* chroots in Copr?

It will stay in Copr as long as people will need it. I may start asking around this time next year. But for next 12 months do not expect a change.

On the other hand we still have epel-6 enabled. And I checked several former users and it seems that no one is using it. Therefore we will disable epel-6 soon.
