Thanks for the response.

 

Unfortunately, I can’t use #raw in this particular instance.  I shortened the code to demonstrate the problem, but I use the same construct in another couple of places, and I need to have variables expanded in general.  I just want to specify that this particular string has dollar-signs but is **not** a variable.  I thought single-quoting would do that, but apparently I was wrong.

 

Also, thank you for the link.  The link I had (http://www.cheetahtemplate.org/) is apparently way out of date.

 

I eventually found a work-around:

 

#set $crypted_password = '$1$abcdef$abcdefghabcdefghabcdef'

rootpw --iscrypted $crypted_password

 

but I’m still confused as to why the behavior is different.

Hi

https://pythonhosted.org/Cheetah/

Try

#raw
#end raw

around your password line with $ in it.

Greetings.

 

I have two cobbler systems running 2.6.5 and 2.6.11, and both are exhibiting this same behavior.  I don’t know if it’s something I’m doing wrong, or just something I don’t understand.

 

My default kickstart calls a snippet called “set_password”.  The default “set_password” snippet, located in /var/lib/cobbler/snippets/set_password , includes this line:

 

rootpw --iscrypted '$1$abcdef$abcdefghabcdefghabcdef'

 

That works fine.  So far so good.

 

But when I take this same **exact** file and copy it to /var/lib/cobbler/snippets/per_profile/set_password/support , then the snippet fails.  It is trying to expand the non-existent variables $abcdef and $abcdefghabcdefghabcdef  .  I can verify this by changing the two dollar signs ($1 doesn’t seem to be affected) and the snippet loads properly.

 

So I guess my question is two-fold

 

Which is the correct behavior, in a single-quoted string that contains dollar signs?  Extrapolate the variable or don’t?

 

Why is this behavior changing between a default snippet and a per-profile (also for a per-system) snippet?

 

Thanks.
