Hmmm, are you using resolvconf? That is a stand-alone helper tool that
allows synchronization between various tools that intend to update
/etc/resolv.conf. There's --enable-resolvconf flag in configure script.

It should. I need to check that, but it looks like a regression after
recent merge of the resolvconf patch. Most probably it's a bug.

Good! It should do that, as the DNS_SERVERS option does not offer such
opportunity. See RFC3646 for details. IPv6 addresses only.
Please use DHCPv4 client to configure IPv4 addresses.
On a side note, one of the goals of Dibbler is to hasten IPv6 adoption.
I personally have zero interest with touching IPv4. I consider it a
legacy technology :) That's one of the reasons why things that possible
could be done over both protocols (like DNS Updates) are exclusively
