If Fred declines, is anyone free to take you up on the offer? I have
no filesystem experience and almost no experience with kernel code in
general, so I would not be anyone's first choice for a task like this.
However, since it mainly appears to be an integration exercise (using
the code from GRUB and making it work in linux), it might well be
doable for me. As a bonus, being highly inexperienced, I have no
expectations of doing anything correctly, and thus would not react
badly to lots of criticism.

So to summarize - if anyone else would like to undertake this work,
they probably should. But if no one has the time/will, then I would
be happy to give it a try.
