I think I understand better now. Yes, I agree that it would need to be
programmatic and reliable. Would be great if there was a way to detect
modules that have firmware requirements, but I think you mentioned
earlier that it's not.

This might be a result of me being naive about when firmware is really
needed or not. If it is safe to say that it is only ever needed for
bringup on bare metal then I think doing the provides in fedora-release-cloud
would be the right thing to do.

Thanks again for being patient,
