Thanks for all the replies and apologies for the non-threaded reply as I had subscribed to the digest version. I went with the solution above from Peter since it was simple and addressed my main need. I had to make one small correction, /sbin/ifconfig did not exist in the kickstart boot environment, it was actually at /usr/bin/ifconfig. So I removed the /sbin/ from the call to ifconfig after which it worked fine. 

Cheers,
Pat
