When checking the server health, katello-change-hostname uses `hammer ping`, a command not available on capsule. The script should be checked so that it is ready for use on capsule servers.
Thanks Brad, I made a note to take a look at this -John
Peter, I'll look at cleaning up the terminology, thanks for catching that. As far as workflow for a capsule, you can generate the certs with a new fqdn, copy the certs over, and then run katello-change-hostname with --certs-tar
