How to launch Dogtail script from within Anaconda

[Alexander Todorov <atodorov@xxxxxxxxxx>]

Hello,
I would like to gather some ideas what is the best way of launching 
dogtail testcases from anaconda.
Suppose we have all the required files in stage2.img.

My thoughts:

Supose we have dogtail="something" option in anaconda.
The execution gets to the point where we have to download the testcase 
and run it. In the moment I use two files. One is the testcase 
(testcase.py) and the second one is a helper (launcher.sh).
My launcher sets up the environment (e.g. export DISPLAY=:1) and then 
executes the testcase.
I could use it to copy the logfiles after the testcase has finished.
The good thing here is that I have my testcase containing dogtail only 
stuff. All other actions are left to launcher.sh

The other approach is to have anaconda execute testcase.py and leave the 
testcase developer take care of environment.
We can have some helpers to ease testcase development of course.

What do you think is the best approach here?
I would like to hear other people's opinion.

Greetings,
Alexander.
