[Spacewalk-list] cobbler integration with kickstart variables

[Dallas Graves]

Thanks Jonathan, your suggestion to investigate Cheetah further was exactly
what I was missing.  I've been able to throw in some Python code into my
kickstart file and by passing some variables into Cobbler via the --ksmeta
switch, I've been able to achieve my goal of using a single default
Kickstart profile to apply to all hosts in my environment.  In case anyone
is curious, here's what my solution looks like in practice.

Kickstart variables with the required python code for the Cheetah
templating:
#set $ip_address=$getVar'ip_address'
#set $netmask=$getVar'netmask'
#set $gateway=$getVar'gateway'
#set $hostname=$getVar'hostname'
#set $name_servers=$getVar'name_servers'

...then setting the variables in the 'network' section in the Kickstart
file:
network --noipv6 --onboot=yes --hostname=$hostname --bootproto=static
--ip=$ip_address --netmask=$netmask --gateway=$gateway
--nameserver=$name_servers

And the Cobbler deployment would look like this:
cobbler system add --name=test1.home.local --mac-address=52:54:00:55:a4:99
--profile=centos7_base:1:SpacewalkDefaultOrganization
--ksmeta="hostname=test1.home.local ip_address=192.168.1.99
netmask=255.255.255.0 gateway=192.168.1.1 name_servers=192.168.1.31"

Thanks,
-Dallas Graves
