The post- RHEL 9 GA time allowed us to move the epel-9-* chroots to the
official RHEL 9 + EPEL content (from previous CentOS Stream 9 + EPEL 9).
Should you have any problems with RHEL+EPEL 9, please report.
Just to recap, it means that EPEL 9 chroots use similar principles to
previously moved EPEL 8, while EPEL 7 still uses (supported) CentOS 7:

Description in the "project -> settings" (and "$ copr
list-chroots") were
updated accordingly to self-document.
Happy building,
Pavel
