Inode #1 was (a long time ago) a "file" that contained nothing but bad blocks.

Most system's don't use this any more, but they still reserve the number.  I'm
sure that there's some brain damaged (;-) software out there that thinks that
inodes start at #3.

Yes, to the best of my knowledge, inode #2 is always the root of a mounted
filesystem.  (Inodes #'s are unique to each filesystem.)
