This third part is open for debate: it is using some Gujin exported
variables to search for the root filesystem: Gujin knows from which
disk/partition it loads the KGZ kernel file - and so the real mode
kernel function can deduce where is its root if it knows the order
of the IDE interfaces and the initial name of the kernel at GZIP
time (either "make /boot/kernel.kgz" or "make /kernel.kgz" with or
without a separate partition for /boot).
