Quoting Kelsey Hightower <kelsey.hightower(a)gmail.com>:
Using the following in my kickstart template, I was able to render
the mac
address for eth0:
$getVar('$mac_address_eth0')
Confirmed working using the following command which prints out the rendered
kickstart profile:
cobbler system getks --name=<system_name>
This works perfect, Thanks a lot,
Luc
