I am a little late to this thread, but saw Hubert's comment about the
needed ls in cd9660. When I made my live CD I added this ability, and
the ability to boot a large kernel in non-emulation mode from a CD.
My changes for non-emulation require a new /boot, so I don't consider
this ready to turn in. However the changes for ls could be used (although
their is 1 hack for printable entries). Attached is the patch to 2.1 code:
