Now that I think of it, overwriting the same inode isn't good either, since
we can't garantee that the change will be atomical (and datafiles currently
in used can have an intermediate "corrupted" state).

Can we have it remove the link, and then reset all other links from the old
inode to the new one, or is that completely insane?
