getVar (outside of #raw/#endraw, those will prevent Cheetah/koan
interpolations) I thought would retrieve any value that can be seen via
'cobbler system dumpvars -name=<client>'.
In my case, I see profile, profile_name, as well as distro and distro_name.
The kickstart can be found in the kickstart variable. I can pull in the values:
>From a kickstart file:
# Test getVar $getVar("profile","No Profile")
>From the generated kickstart:
# Test getVar dev-rhel5
My immediate suspicion is that you have an unclosed #raw tag somewhere above.

Subject: Re: [Spacewalk-list] Using getVar in a Snippet
Uncertain about the getVar commands. However the ks= can be found during the
kickstart in /proc/cmdline as it has the entire command line that was sent via
the anaconda boot options. This would include the ks= and other variable that
can be obtained as well. ie. ip, gateway, netmask, nameserver and any other
misc custom flags (do not have to be valid boot options) for %post snippets.
So, this information could be written out to a file during the server
kickstart. There may be some better ways to do this, but using /proc/cmdline
has worked for years and continues to do so in Cent/RHEL 7.x.
%post --nochroot
cat /proc/cmdline > /mnt/sysimage/xxxx/xxxx.out
%post
cat /proc/cmdline > /xxxx/xxxxx.out
ksurl=`awk -F"ks=" '{print $1}' /xxxx/xxxxx.out |awk '{print $1}'`
ks_profile="${ksurlf##*/}"
or if cobbler or Cheetah has issues with the above...
ks_profile=`echo "$ksurl" |rev |cut -d"/" -f1|rev`
- Thanks and good luck

Hi Folks,
I am trying to determine profile used to kickstart a particular machine, I have
tried every version of $getVar that I can think of:
(I started with the one in an example on the
https://fedorahosted.org/cobbler/wiki/KickstartSnippetswiki page)..
#set $p = $getVar('$profile')
That didn't work, so I have tried:
#set $p = $getVar('profile')
#set p = $getVar('profile', 'None')
#set p = $getVar("profile", 'None')
I noticed in the post_install_network_config snippet, they use BOTH:
#set osversion = $getVar("os_version","")
and
#set $numbondingdevs = 0
(Note the use of $ in the 2nd set command...what's the difference?)
Added #raw/#endraw ... that didn't matter.
Help...please?
Thanks in advance.
-Emmett
