My goal is to access a variable within Cobbler, $hostname for example,

Below
is some pseudo code to demonstrate my aim.
os.system("/usr/local/sbin/dostuff.sh $hostname")
Cobbler passes the name of the system as the first argument to the
command. If your system name is the hostname, then in python you can
just use something simple like:
machine = sys.argv[1]
If your system name is not the hostname then you can query the
hostname of the system from Cobbler. Here is some python code I've
been using:
from cobbler import api
cobbler_api = api.BootAPI()
systems = cobbler_api.systems()
box = systems.find(sys.argv[1])
I'm sure there are other (and probably better) ways as well.

Right! I added that example here --
https://fedorahosted.org/cobbler/wiki/CobblerTriggers -- so other
people could find it when they were
reading the docs.
Thanks!

Thank you for all of your help. This is what I came up, not sure how
optimal it is, as I do not code python.
You do now :)
========= getcert.trigger - add/system/post trigger ===========
#!/usr/bin/python
import os
import sys
from cobbler import api
cobbler_api = api.BootAPI()
# this is the systemname, not the hostname, so be sure to use the FQDN
in the systemname
machine = sys.argv[1]
# location of getcert.sh script
getcert_cmd = "/usr/local/sbin/getcert.sh"
# set return code to 0 by default
rc = 0
# build the command string
cmd = getcert_cmd + " " + machine
# log to cobbler's logs
cobbler_api.log("running - " + cmd)
# run the command and set the return code
rc = os.system(cmd)
# exit with return code
sys.exit(rc)
==== end code ====
This allows me to run a script when I add a system that will
pre-generate puppet certs.
