dhcpd: How to automaticly get it to use dns servers from eth0?
 

Is there anyway to get dhcpd to automaticly pass on whatever dns servers eth0 gets from my isp? Right now I'm using:
option domain-name-servers (isp's dns servers )
in dhcpd.conf and thats working just fine I'm just wondering if there is a way to automate this in case they change etc..

Thanks
