Well, not yet, I need to get a patch added that will add the relevant 
info to dns_update_list, so that samba_dnsupdate can add all the 
required dns info when a new secondary DC is started for the first time.

I seem to have a problem getting patches past, I was advised that it 
might be quicker using the new Github method, but this doesn't seem to 
be true, I have seen faster glaciers. :-D
