I'm not sure how stable the unionfs system is.. or if it will become a part of the kernel tree that quickly. I just want to know of the unionfs.ko is present in a knoppix hd install. Also when knoppix installs, is it an uncompressed image or does it do a poor man's install with a compressed image? I've got a unique system using a CF (8GB) for a hd. I just don't want to burn up the CF with writes in the process.
