Hi @astrava,
No difference whatsoever:) One is a symlink to the other. This is because we need to support both CentOS and RHEL. In CentOS, $releasever is set to the distro major release version only [i.e: 6, 7 and one day 8] whereas in RHEL it is set to the version number suffixed with ‘Server’ [6Server, 7Server].
Since we need this:
baseurl = http://installrepo.origin.kaltura.org/releases/nightly/$releasever/RPMS/$basearch/
To work with both, we have symlinks.
