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.

Nice with feedback.

And I think that Pete's solution was KISS and I love that design regime.
