Sounds OK with me, but why stop there? Make every part of the kernel
internals a module. Then, to upgrade a system, one unloads everything except
the module code, then reloads all the new modules except the init module,
then loads the init module. And boom, it boots again. :) So upgrading is
only necessary when updating the module code.
I'm sure this is just as easy as it sounds. :)
