Mattia, when you say you have the patches, which ones?

To be clear, the RDNSS/DNSSL support that was committed to head was
very heavily modified from that which I proposed and which is on my
web site.  In particular, the resolvconf(8) tool that I offered was
not used at all; the version in head is the openresolv tool by Roy
Marples.  Doug's response is in regard to the resolvconf version
in head.

FWIW, the resolvconf version from my site will use the most recent
nameservers received by from either dhclient-script or rtadvd but you
can also add "static" entries using standard resolv.conf syntax in the
/var/db/resolv.db file; see the man page with that version.

I will update my RDNSS/DNSSL web page now to add a warning that my
patches have been superseded and that folk should use the committed
versions where possible.
