    Sure, that makes sense. Done.

    Yes, it was sort of a future-proofing if SRV records are ever made


Could I request an option to not add _srv_ at all, like a
--no-dns-discovery option.  This way those of us who unfortunately are
in situations where we can't create SRV records at all can have it
designated at install time?  Otherwise I have to edit the config files
afterwards anyway to get rid of it.

It could be made default false, of course, but if set the _srv_ entry
would not be added.

You'll be able to do that by specifying --server and --fixed-primary.
