Hey Marco,
Do you have the kickstart up somewhere? I'd really like to rebase soas-1 on it, having a small image would be awesome for the XO. I suppose it's not based on fedora-live-base?
Sebastian's kickstart files are here:

I agree that we should use (or at least merge) them, there's a lot of great work here.
Thanks,
- Chris.
