No, it isn't a 'warning', it is a notice. It is just telling you that
there is a 'krb5.conf' file that you should use. This is a part of the
'provision' code that runs during the 'join' and can be ignored in this
case, because the join wouldn't work if krb5.conf wasn't set up
correctly.

Very strange, it looks like it is trying to add a dns record to a zone
that doesn't exist, does the Windows DC you are using to join to the
domain run a dns server ?
