I would LOVE to make the EPEL repos available to build against in the
CentOS buildroots. I think it is a solid idea.
...
Certainly for SIGs, I see no reason not to do it for CBS and/or any
other SIG building location.
Yes, that's a better fit for how many people want to consume Storage SIG packages.
E.g. Ceph's upstream CI builds using EPEL packages. And a lot of other consumers of Storage SIG packages are using EPEL, and we sometimes run into conflicts when they have EPEL enabled.
For C8 Stream I would have preferred to not have to build the two dozen or so dependencies before I could build Ceph itself.
So +1 from me on being able to use EPEL in CBS for SIG packages.
