Well, linuxrc and a number of aspects of the boot process seem to suffer
from attempting to kludge userspace programs into the kernel.  To this
end, I would like to propose that we move these functions into userspace
where they belong and instead provide support for linking an initial
filesystem image into vmlinux.  We can then move linuxrc, dhcp and other
such bits out of the kernel and use the same code as is normally used at
run time -> it's better tested and easier to fix.
