This is a big liveDVD, and it seems to be unable to compile. Annonaceae, which is a smaller image, compiles fine though.

I think the problem lies with the line that controls image size in cherimoya.ks

part / --size 20000 --fstype ext4

It's probably too small for the liveDVD, but I'm not sure how to fix it.

Maybe we need to see how the Fedora developers worked with it in their kickstarts:
