But it does it by making it build.  8-) 8-).

Yes, of course.  The main sticking point is that the boot blocks
booting an ELF kernel can only boot an ELF kernel, so dancing back
and forth, back and forth is a bit out of the question.  Yes, the
current boot hacks fit (barely; < 80 bytes remaining), but don't
cover all the cases the a,out-only boot blocks do.

The LKM situation is equally grim; the LKM's must be switched at
the same time.  This is because the LKM relocation is done by
linking against the kernel symbol table.  Try linking an a.out
image against the kernel symbol table.
