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 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?

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).

Support for EL4 should be maintained until EL4 is EOL. It's only got 2 years left. I believe it's EOL in 2012. As for templating, I agree that there needs to be specific reasons for the change. The various and other problems should be detailed. It's possible that there are less drastic solutions to those problems. I'm not personally invested too heavily in Cheetah. I like Genshi for a number of reasons, but would be open to adapting to other options. I'm not opposed to learning something new. :-) There's been a few blog posts going around Planet Python in the last month about good and bad uses of templating engines. With cobbler-web having moved to Django for cobbler 2.0 (IIRC), it sort of makes sense to move the rest of the app in that direction as well. However, if this happens, I think it should incur another big version bump to 2.5 or 3.0, so that it's clear that this isn't just a minor update. sharing the same view.

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

Re: Hello from Ubuntu land
The problem with the debian imports (ubuntu also if I'm right), is that the media import cannot perform all tasks that a redhat does. The media is built (was at least) for device attached installs, so kernel+initrd are no network aware. The ones required for pxe booting must be downloaded separately. Some of the possible workflows were Recent Ubuntu Server CD's (the one below is 10.04.1) come with everything you need to netboot: I didn't know that. It's good for ubuntu and probably also for derived distros, but not for debian. And this gets more complicated as debian does not care very much about the released vs. updates structure, so either you move your imported packages into your repository-mirror directory or you will download again all the media contents into your local mirror. Can you explain exactly what this means for users? The way I understand it.. one imports the contents of a CD, and then one can also import packages from a repository for, say, updates. Right? How would the debian/ubuntu way of specifying packages inhibit this? One can feed multiple sources for an install into debian-installer with preseed files with d-i apt-setup/local0/repository http://cobblerbox/ubuntu lucid main restricted d-i apt-setup/local1/repository http://cobblerbox/ubuntu lucid universe d-i apt-setup/local2/repository http://cobblerbox/ubuntu lucid-updates main Maybe this is also a change on new ubuntu versions, but previous versions (and current debians) do not have a lucid-updates repository. Updated packages are mixed with those initially released in the same tree. So, when importing a media the contents must not go to an install tree but to a repository. Or the repository must live wherever you have your install tree.

Thirded, but with the caveat that setting up some transition now would be good too. We could start moving templates over and still support cheetah, but eventually all of the templates that ship with cobbler would be in the new templating language. The only difficulty would be identifying which kind of template a file is ahead of time. ___ cobbler-devel mailing list cobbler-devel@lists.fedorahosted.org https://fedorahosted.org/mailman/listinfo/cobbler-devel
