Rendering oddness in 2.4.0

[Corey Kovacs]

I recently bestowed the virtues of cobbler unto a colleague who has, like
many, decided it's the best thing since sliced bread. Good so far...

After he had been working with it for a while, he experienced a problem
which was keeping his lower per_* snippets from overriding the top level
counterparts.

For example, he has
snippets/post_install
and also
snippets/per_system/post_install/mysystem01.

In both files he had (unbeknownst before the override) unescaped "$" chars.
When the per_system post_install snippet was not applied, everything
rendered correctly. However when a specific host was specified in order to
get the overriding snippet, the rendering failed.

So, to recap, two copies of the same messed up snippet were in place. The
top level one rendered correctly, the per_system one did not as cheetah
choked on the unescaped "$" signs.

Is this a know bug/feature?

No, frankly both of them should have caused issues, the oddity is that the
top-level one did not. Are you sure there weren't any #raw blocks in there?

Thanks James, I understand they should have both failed, that's the issue I
am trying to sort out. I don't believe any #raw statements are present but
I'll take a look tomorrow. Once I handed it over, the guy ran with it and
is a huge fan as am I. So  hardy thanks to all the contributors.

When I commented everything out of the snippet with a  "$" things worked as
expected. But again, it should have failed on both levels. Very odd indeed.
An errant #raw would make sense though so I'll pour though the previous
snippets to make sure something else isn't out of whack.

Thanks again

Newbie setup question.

[Chris Johnson]

Hi.

Is there any documentation on what the standard snippets that come with 
cobbler do, what inputs they need from cobbler, etc?  I'm having trouble 
with snippets network_config and post_install_network_config.  I've 
managed the get the former working (albeit not cleanly) but not the 
latter.  The post install one is giving me grief about the only mkdir 
command in it.  My cheetah and Python aren't that good enough yet to 
really find out all the details of what's going on in these snippets to 
fully resolve the issues I'm having.

Thank you.

Did you try rendering the full kickstart file
cobbler profile getks --name=XYZ...
cobbler system getks -name=XYZ...

It is easier to debug as it shows exactly what the post-install chroot
environment will do.
