Subject: Re: NIS patch for dhcp client

Hi Justin,

Thanks for the patch. Could you send this patch to the dhcp-server
mailing list? That way people can comment on it and I can see the
comments and decide if it is safe to include it in the official Debian
package.

The information about the dhcp-server mailing list can be found at
www.isc.org.

Cheers,

Eloy.-
