Yes, there are, from the perspective of Luke's description.  "level0" refers
to the RDB entries; there's no actual executable code there.  Similarly, the
Sun disklabel is the "level0" bootblock for a Sun machine.

IMHO, I don't think this would be particularly useful, because you'd have to
make it a real AmigaOS object file with relocs (LoadSeg compatible) and deal
a little more with the internals of dos.library.  Blecch...  :)

Really, the reserved-blocks at the beginning of the fs is the best way to
go, since we support that boot method on a plethora of other platforms.
