Tested this a bit and while hard link indexing does work,  inode
lookup is broken since it uses the origin inode as a key (which is not
available) instead of using the origin value directly.  This is
fixable, but needs a fair amount of restructuring, so let's just
postpone this and disable index for now, as you suggested.
