I have another idea on this subject. First, We can extend the function of
grub-mkimage so that it can handle data files. The data files embed in
core.img can be accessed using a special device such as (ed). Then, we can
put all necessary files, such as modules, grub.cfg and other data files in
a single core.img. This kernel is self-sustaining, no extra file is needed
for it to function properly.

Even if we don't create mono kernel, embeded data files can be usefully. For
example, moddep.lst, fs.lst and command.lst, these files are best placed in
core.img. Also, we can check the presence of embeded grub.cfg before loading
external one, this is similar to the preset menu concept in GRUB Legacy.
