How to reenable cheetah 'try' directive

[Jens Ahrens]

Hi everybody,

I just upgraded from cobbler 2.0.3 to 2.0.9 and have the following problem:

In some of my kickstart templates I use the cheetah #try directive. But 
since the upgrade of cobbler, I'm getting an error when trying to output 
my kickstart file:

...
This 'try' directive is disabled
...

Is there any easy way to reenable it. I would not really want to rewrite 
all my kickstart templates.

Thanks and Cheers,
Jens

I found an easy solution that seems to work fine, but I'm not sure if 
this causes cobbler to fail somewhere:

Added 'try' and 'except' to the whitelist in  
/usr/lib/python2.4/site-packages/cobbler/template_api.py
Deleted /usr/lib/python2.4/site-packages/cobbler/template_api.pyc and 
/usr/lib/python2.4/site-packages/cobbler/template_api.pyo
Restart cobblerd

Cheers,
Jens

You can set safe_templating to false.  This is the simplest way.
