I know this may be out of scope for the module, but it was an idea anyhow.. Right now pykickstart supports options for kickstart files that don't exist for all fc/rhel versions. It would be nice if pyckistart was aware of what version of rhel/fc you were writing the kickstart file for so that it would only expose the available options-- This way you could have one program that could write kickstart files for a bunch of different versions without putting in options that anaconda couldn't parse because it's not aware. I guess one would to do it is assign some sort of key -- maybe ksdata.version that would define the version of rhel/fc you are using, and then add meta data to the options so they are aware of what versions that should work with.. As of right now with my program I'm more or less stripping out of the text that pykickstart creates all the options that shouldn't be available, there's got to be a better way.
Well, that was a lot of work. pykickstart-0.90-1 has been built, which contains this functionality. There's still things to do like deciding on a final format for version strings, adding support for various RHEL releases, making a devel syntax version for F7, updating the programmers-guide, and so forth. However I'm going to close this bug since the functionality is now there. Undoubtedly, there are going to be bugs in this (or in anaconda, or s-c-ks because of this). Please file those separately to make it easier to deal with, rather than adding a bunch of stuff to this bug.
Thanks for the hard work.. I will get cracking on it soon!
