My first concern about this is that this library is way to big for
GRUB 2.  The issues for GRUB 2 are different from those of GRUB
Legacy.

Second the library does have stuff like memory management, etc IIRC.
What I remember of it, it is pretty bloated.  Or am I mistaken about
this?

Personally I do not like the idea to use an external library to add a
filesystem to GRUB 2.  I wonder what the opinion of other GRUB 2
developers is about this.

But this did not answer my question about complexity of reiserfs 4.
But I will have a look at it and see what I can do for GRUB 2.

As for GRUB Legacy, that is not up to me.

Thanks,
Marco
