In my testing it would appear for Dynamic DNS to work (update DNS A and PTR

If I have something like, dynamic DNS does not appear to work:

The second /etc/hosts file should be correct but dynamic DNS is not
working. Is there something in the implementation that requires the first
case, or should just the order of the /etc/hosts entries modified so that
the localhost appears second in the list?
I think this is more of a SASL or kerberos issue that requires the
forward and reverse records to match.
But yes, in general with Kerberos, especially not the most recent
versions, you want the DNS records to match in both directions.
