Better,
ks=http://kickstart.example.com/cgi/ks?<stuff to suit you>
ks could take into account the source IP address in framing its response.

dhcpd can be configured to give different responses depending on who's 
asking: PXE can get one set of responses, anaconda another, 
debian-installer a third, Windows can get something completely different.
