stopping domain-name-servers on DHCPv4

[Karl Auer]

I have an oddball problem.

I want DHCPv4 to get me an address, but I do NOT want it to write the
received nameserver addresses into resolv.conf. DHCP is being done by
wicd.

I've already tried several things:

- editing /etc/dhcp3/dhclient.conf in various ways, before realising
  that wicd was managing DHCPv4 with it's own config file :-)

- using the supersede keyword in /etc/wicd/dhclient.conf.template

  The new line appears as expected in /var/lib/wicd/dhclient.conf,
  but the nameservers from the DHCPv4 server still appear in
  resolv.conf. I've tried an empty nameserver address (""), an IPv6
  address, and an IPv4 address.

- adding a modified request line to /etc/wicd/dhclient.conf.template

  The new set of requested items, minus the domain-name-servers item,
  appears in /var/lib/wicd/dhclient.conf as expected, but the
  nameservers from the DHCPv4 server still appear in resolv.conf. I.e.,
  the server is sending them even though the client is not requesting
  them, I guess.

I thnk resolvconf is interfering, but I can't see an easy way to tell
resolvconf how to behave. The script
in /etc/dhcp3/dhclient-enter-hooks.d seems pretty simpleminded. I
disabled it, but the supersede line in wicd still had no effect.

Basically I'm not too sure what's actually going on. Any clues
gratefully received.

Regards, K.
