Ahh, okay, that works. Might be worth mentioning in the manpage though.
Maybe an example wouldn't be too bad either

Of course, once 1) is solved 2) is redundant.

Hmm, not sure what happened last time here, but I've tried it now with a
single nameserver, a space separated list of nameservers and a mix of
name_servers and name_servers_append entries and it worked perfectly.
It also eliminated duplicate entries in name_servers and
name_servers_append, preferring the one in name_servers. Again, maybe
worthwhile mentioning in the manpage.

Yes, got it. All good! Thanks to all!
