This looks really interesting. A while ago we looked into "overlay
filesystem" patches for the kernel. The idea was to mount the
RO-filesystem and mount a writable filesystem (e. g. RAM-disk oder
harddisk) on top of it, so that writes would become possible. At that
time the development of the overlay filesystem was stalled.
If this translucency really does what I think it does it could
revolutionize the way Knoppix works. At the moment Knoppix uses the
RAM-disk as / and copies files that need to be writeable and links
other files to the CD-ROM. With this patch on could perform the
changes on the CD with no need for all the symlinking.

Even if Klaus didn't make this default as I suggested above I don't
think there are objections to at least adding the module. None the less
you should find the .config-file used for the kernel in /usr/src/linux.
