I may be talking through my hat, but I've heard that this is a really good, and easy to use installer, and Novell has decided to release it as open source.

Might be nice for noobs if it doesn't eat up too much room in the ISO. I haven't had the nerve to try knx-hdinstall or knoppix installer - so they may be just as good.
