I received a copy of this email (with a different message-ID)
personally, and I replied to it personally.  Here's my reply, because I
think it may be useful to others.

Sure, get root and hack the DHCP scripts in /etc to update
/etc/resolv.conf.

Whoa.  Now this works for me.  Are you sure your DNS/DHCP servers are
configured properly?

Shouldn't matter.

Yes, hack the scripts in /etc/udhcpc/.  I think the only file that is
actually used is udhcpc.script, but that's my personal guess.  Add
something like

    echo nameserver 127.0.0.1 > /etc/resolv.conf
    echo search $domain >> /etc/resolv.conf

to the 'bound|renew)' part in the case statement.

Uh, I'm not responsible if fiddling with that file breaks your N770. ;)

I don't have one yet.
