Sounds like a neat project! Did you have a question in particular? I assume you're already looking at ext2 docs and source to find unused areas or areas where more than one value can have the same meaning. For source, I like the ext2 implementation in GRUB bootloader as a rough example because it's read-only and a little simpler, it is usually easy to worry about reading first then worry about modifying/writing when dealing with a new filesystem. -- Jon Mayo
