Actually, my kickstarts run with the DNS info provided by my DNCP server. The only thing that I've had to do is copy the created /etc/resolv.conf file into the newly-built tree so that it's available to the system for running "post" scripts.
thanks for the reply - these are statically assigned kickstarts and DHCP is not involved - you can pass a DNS server to use as dns=1.2.3.4 but there appears to be no search=foo.com etc
AFAIK
