Well, it took me a while to understand that I actually needed to list every
(ffs-derived) filesystem explicitely.  ;)

Well, there's i386... the missing interaction with OF makes it quite different.

That's more or less what I ended up with. The small problem: It doesn't
work, a kernel on an lfs partition is not found. The fact that there's no
way of looking at the file systems in question, and no diaglostics, doesn't
help either.
