Missing manual page - reported bug 1495567
Upstream bug assigned to firstname.lastname@example.org
You only have to update short hostnames if you are using short hostnames instead of your FQDN, FQDNs are automatically updated.
I'll look into the issue you ran across more in detail. Just to confirm, the katello-change-hostname command was successful?
I'm sorry I have not checked is exit value, but there were no obvious error in the output.
Moving this back to ON_QA, please retest in the upcoming snap
