I'm considering a move off of Cheetah as the templating language for
Cobbler. I am personally leaning towards django or jinja(1 or 2
depending on the EL4 discussion). I would like to know opinions people
have on if we should move and what we should move to.
Additionally, I'm considering if we should continue to explicitly
support EL4 for running Cobbler on. This would be due to the fact that
many of the really nice templating languages are just not supported on
the version of python that EL4 runs. We would continue to support
running koan on EL4 (in fact I think we will still run all the way back
to AS2.1). Are there people that are still running Cobbler on EL4?
Thanks.

Actually yes I still am running EL4.
Out of curiosity what do you find is a problem with Cheetah?

Cheetah recently broke on F14 and has had various and other problems
with its security. It has generally just been a pain in my back side
for some time. I'm not saying I'm going to make a change, just trying
to get a general feeling on the subject at this place.

+1 for dropping cheetah moving to django and not having to support
Cobbler running on EL4.

Asunto: New templating language and support for EL4
I'm considering a move off of Cheetah as the templating language for
Cobbler. I am personally leaning towards django or jinja(1 or 2
depending on the EL4 discussion). I would like to know opinions people
have on if we should move and what we should move to.
Additionally, I'm considering if we should continue to explicitly
support EL4 for running Cobbler on. This would be due to the fact that

I plan to run cobbler on EL4 while we migrate over EL5, but it depends on being able to
get RH's httpd instead of user provided apache 1.3.1. Not sure about deadline, but if
finally proceed, we'll be migrating over EL5 during next year.
One of the problems we've is the templating part of pxelocal.template which
doesn't uses pxe_menu_items to render file (on cobbler list).

Pablo

I'd love to see this. Any language which uses a single '#' for a
comment and a double '#' for an instruction is just plain dumb in my
opinion and is one of the reasons I don't use templating in my kickstart
files - too much room for human error.
The Django style of templating would be awesome, it makes far more sense
to me than Cheetah does, so +1 for Django.

We're only running EL4 on a few webservers and we've made a rule that
EL4/Centos4 isn't going anywhere near our production kit or cobbler, so
it makes no difference here... :)

We make extensive use of templating in our environment so this would
require tossing a bunch of work. I'm not saying it's a bad idea, but
what problems are you solving with this change? Cheetah may not be
the Best Thing Ever, but it's simple to learn and reasonably
functional.
I guess I'm wondering if this is a "if it ain't broke, don't fix it"
situation.

We make extensive use of templating in our environment so this would
require tossing a bunch of work.
We use cheetah-templatingscripting, but from time to time we
miss functionality and usually solve this in using the missing
things from the shell on actual deployment.
Uning different templating-language would require the effort
to rewrite things, yet for a more powerful language it would
be worth it.

Cheetah is simple, but quite messy and confusing. The confusing thing is
the # at the beginning of each command while a # in front of a entry in
a ks file is a comment. Mixing those two thing ends up in a mess.
Additionally, debugging Cheetah based snippets is a nightmare.
I do not know about django or jinja. Maybe it would be a good idea to
publish some mock-ups of snippets based on those two templating engines.
It also means quite some work to migrate all the snippets in place to
the new templating engine. So old Cobbler versions with Cheetah should
be maintained for some time to give people enough time to migrate.
At the end of the day, I think it is a good idea to switch.

As EL4 is quite old and soon reaching its end of the life cycle (Feb
2012 w/o considering ELS) I think people can life with some updates for
severe bugfixes for Cobbler on EL4. (Lets say for Cobbler 1.6 and maybe 2.x)
For cobbler with a new templating engine, lets say Cobbler 3.0, IMHO it
should be based on EL6.
Thanks,
Luc

I use Cobbler on EL4 (can't upgrade it until next year). However I
agree with Luc. Having a new version of Cobbler base on new EL make
sense.
The change to Cheetah would be a bit more problematic given complete
rewrite of a lot of snippets. However that is also doable, as I don't
have to upgrade Cobbler until time permits to make those changes.
I also second Luc request for some sample Django snippets to see what
the change would be.

Based upon the response, I am definitely going to keep EL4 support.
I am also inclined not to make a change the template language. People
seem reasonably happy with Cheetah and have a reasonably large code base
of templates that we wouldn't want to disturb. Though, I do think
making the template selectable at some point in the future would be a
good thing, at this point in time I'm not going to put any time into
changing it.
