Correct, I just removed the real life IP's from habit. The build
network (eth1) are from private IP address space, and the eth0
interface IP's are public IP space.

Ah, that's the hint I think I needed - and have now found the section
in the wiki. I was not understanding the use of the $ip_address_intf0
variable. Obviously I wanted to keep the ks files as generic as
possible (all the systems are pretty much built the same), with just
the IP's changing. using the 'cobbler system add' seemed the best way
to do this.
thanks for your help,
Matt
