[et-mgmt-tools] no substitution for ip_address in kickstart file

[Terry McIntyre]

I have a cobbler 1.4.1 installation, and recently a kickstart failed.
Looking at the
http://my.host/cblr/svc/op/ks/system/sapcps kickstart file, I find this line:

network --hostname=sapcps.mydomain --bootproto=static
--netmask=255.255.254.0 --ip=$ip_address --gateway=192.168.62.40
--device=eth0 --onboot=on

The source line in /etc/cobbler/sample.ks is:

network --hostname=${hostname} --bootproto=static
--netmask=255.255.254.0 --ip=$ip_address --gateway=$gateway
--device=eth0 --onboot=on

$hostname and $gateway are expanded; $ip_address is not.

These values come from /var/lib/cobbler/config/system.d/sapcps:

What am I missing?

Thanks for any assistance.
