Current line 102 includes ### RHEL 8.1 or later. (This PR adds a section: ### RHEL 9 or later)

Can we replace with ### RHEL 8.x

Hi @mjang,

Could you please clarify how your comments relate to this PR? It would be helpful if you could point out the exact location I should look into.

Also, could you explain what the second .repo file refers to?

Where in this PR are we referencing CentOS 7?

I couldn’t find any mention of baseurl=https://pkgs.nginx.com/app-protect-x-oss/centos/7/$basearch/. Could you point me to where it’s being used?
