iirc, someone thought using it for bad blocks would be a good idea,
but then quickly discovered that the only bad blocks you can assign to
inode 1 are data blocks -- not inode blocks (which are unfortunately
not prohibited from going bad) -- so this turned out to be of limited

i seem to have gotten the idea from somewhere that white-out files use
"inode 1" (in much the same way that empty slots use "inode 0")
instead of an actual inode, but i have no idea where i heard that...
