Sounds fine to me, assuming things work like we discussed about.

There is the root variable, but IIRC there were some problems or so.
Anyway, it is how it will work. :)

HFS+ supports symlinks, FAT does not (unless you use UMSDOS, which is
not supported).  For every symlink capable filesystem GRUB 2 supports,
symlink support was implemented.

Personally I do not care very much how it will work in practise.  The
main important thing for me is that we can support both of your
proposals.  I think we just have to try both, when possible on many
different machines.
