Thank you guys! This helps a lot. I will play with triggers and finish this last piece of the puzzle before full production.
I would love to see your scripts, btw.. please unicast them to me, I will probably have to delve into python a bit since I will require cobbler variables to be passed. If wget doesn't work, how do you call the trigger? In the examples I seen online the wget was the method.

However either it's Friday or my brain is fried or..maybe it's just that Python is not my language.. but I don't get it. The documentation to me is very unclear as to what really happens. Do triggers run on the cobbler server? So for instance let's say I have something like this in a trigger: Stupid_trigger.sh #!/bin/bash echo "success $hostname is done" >> /tmp/file (to pick a really silly example). Than when I run something like: wget "http://$server/cblr/svc/op/trig/mode/pre/system/stupid_trigger.sh"; -O /dev/null that will run on the cobbler server? Finally if above is true, can trigger gain access to the cobbler/cheetah template variables, or do I have to stand on my head and do rain dance to get variables? (yes it's Friday brain melting...)

Anyway, do any of you know how I can run a script on the cobbler server after installation? I.E. when installation is finished, I want to run a script on the cobbler server. I can't seem to find a way to do that.
