FS: write ability

I'm going to code new grub2 mechanism to provide not only read, but write
ability to grub loader. First of all i need such feature for ext2/3 FS, but
i think it'll be great to enlarge it to all supported FS.
If anybody can help with some code or recommend interesting approach - feel
free to tell me

Thanks!

Please understand that this cannot be included in GRUB 2, at least as
far as I am concerned.  Although it is very nice to work on write
support, it goes beyond the goal of a bootloader.  If it is included
in GRUB, it means we have to maintain it.  We already have a lack of
time to maintain the current code base.

Besides that, there is little added value.  While write support is
*very* complex, can damage filesystems when there is a bug, etc.  It's
also a lot of work, even for a single filesystem.

Why do you need write support?  Perhaps there is another solution to
the problem you are trying to fix?
