Using variables in kickstart script

Hi

I'm using Mike's UDA to install ESX hosts. The script I have is about 260 lines at the moment. For each host I copy this script and change the IP / hostname and vmotion IP. To do this I have to search through the whole script and hope I don't forget anything.

Is it possible to use variables? I would like something like this:

ks.cfg:

HostIP = "172.x.x.x"

HostName = "vmesx022.mydomain.com"

VMotionIP = "172.x.x.x"

\# Network Configurations

network --device eth0 --bootproto static --ip $HostIP --netmask 255.255.255.0 --gateway 172.29.26.254 --nameserver 145.70.12.203 --nameserver 145.70.11.203  --hostname $HostName --addvmportgroup=0

Can this work?
