Variable expansion in kopts?

[Bryson Lee]

Hi,

Is there a way to get Cobbler (2.0.9) to expand variable references in a 
system's kopts setting?  I have number of systems that are configured 
with static IP addresses, and I'd like to have the network settings 
inserted into the "append" line in the Cobbler-generated yaboot.conf files.

I found Ticket #21, closed years ago, that states that an 
'@@variablename@@' syntax is honored in templated contexts, but when I 
tried it, the '@@var@@' references showed up unchanged in the 
/var/lib/tftpboot/etc/xx-xx-xx-xx-xx-xx file.

Has another syntax superseded '@@var@@' for this purpose?

Thanks,

-Bryson

I believe if you do 'cobbler system edit --name FOO --static True' you
should get what you want.

That doesn't appear to be the case; here's the yaboot.conf that gets 
generated for one of the systems in question:

# yaboot.conf generated by cobbler
init-message="Cobbler generated yaboot configuration.\nHit <TAB> for 
boot options"
timeout=80
delay=100
default=linux

image=/images/fedora10-ppc64/vmlinuz
     label=linux
     initrd=/images/fedora10-ppc64/ramdisk.image.gz
     append=" ksdevice=bootif lang=  console=hvc0 text serial kssendmac 
  ks=http://x.x.x.x/cblr/svc/op/ks/system/ps710-01"

and (parts of) the corresponding system record:

[root@gw2 etc]# cobbler system report --name ps710-01
Name                           : ps710-01
Comment                        :
Gateway                        : x.x.x.1
Hostname                       : ps710-01
...
IP Address                     : x.x.x.251
Static                         : True
Subnet                         : 255.255.255.0
