2011-10-20 I heard about rdnssd today at the NLUUG ...
I heard about rdnssd today at the NLUUG meeting I attended. I gave it a try on my laptop. As an ubuntu package it uses the resolvconf package. I had to change the /etc/resolvconf/interface-order file to use the rdnssd results before the dhcpv4 answers:
# interface-order(5)
lo.inet*
lo.dnsmasq
lo.pdnsd
lo.!(pdns|pdns-recursor)
lo
000.rdnssd
tun*
tap*
hso*
eth*
ath*
wlan*
ppp*
*
And now I get the resulting /etc/resolv.conf I want:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 2001:980:14ca:42::694
nameserver 10.42.2.1
search idefix.net koos.koffie.dot
And resolver traffic goes over IPv6.

Update 2011-11-25: Trying the same on a workstation on the wired network doesn't give the right result:
$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
Yes, empty. No data from rdnssd and no data from dhclient. Back to the working config...
