I don't think this area has changed recently, but perhaps we now catch
the error better. I agree, this is a bit silly - it is writing out a
config file for bind 9.7, ie before we had the DLZ code.
The whole thing needs to be removed - those running bind9 with the
flatfile backend are unsupported anyway and probably don't want Samba
dynamically updating configuration entries - they want things locked
A patch to remove rndc from source4/dsdb/dns_update.c would be
favourably considered. My one concern is that this is accidentally
helping ensure new zones appear in BIND9 with DLZ by poking it every 60
seconds, when these are added over RPC. That should be checked.
