 +==== RHEL in Sepia ====
 +Because RHEL ISOs are only available inside the Red Hat firewall, we can't add an ''http'' URL to the secrets repo.  To add a RHEL version:
 +
 +  - Find the ISO hosted inside the Red Hat firewall and download it
 +  - Once downloaded, ''scp'' the ISO to ''cobbler.front.sepia.ceph.com:/iso''
 +  - In the ceph-sepia-secrets repo, set the appropriate ''%%file:///iso/path%%''
