This is one of those sacred cows I was talking about...


ELF is going to get us part way there, and it's a "large change
relative to the current way things are".

The big issue here is *only* the boot blocks, since aggregation
is a matter of "what is default in the kernel" and "what objects
are linked into the 'installed' subdirectory from the 'available'
subdirectory".

A secondardy issue comes into play *only* if you want to dictate
the ability to change the agregation of a post-linked kernel.  I
personally feel that this is a worthwhile goal, even though it
means that you must place discrete drivers into discrete ELF
sections so that an image archiver can insert or extract them at
will.

If there's a "config" after this point, it's a UI to toggle hard
links and an ELF image archiver interface to be called when the
user selects "create a custom kernel".
