I didn't look at grub2/fs interface yet, but believe that it
is better then grub1's one.

There is a patch for reiser4 support in grub1. I don't
think it will be a big problem to adjust this one for grub2:
the sources are quite understandable.

The only thing I am unhappy with is that it can not boot
reiser4 via module stage1_5 (it is too big and can not
fit in 62 sectors), It means that user will need to re-install
grub every time after defragmentation (currently
unsupported, but upcoming). So it would be nice to resolve
this problem in grub2 somehow.

Btrfs stage1_5 module with multi-device support
successfully fits in 62 sectors. Why reiser4 can not?
I think we need to get rid of the mini-library with a lot
of unneeded functions and put everything in one file
(as other file systems do).

Thanks,
Edward.
