I don't really like this, because links can also be used for other
purposes than "copy on write".  Most importantly your patch breaks
symlinks, which is usually the wrong thing to do.

In my opinion, the use of hardlinked trees is just risky business that
requires a lot of care, so I think priority should be given to handle
the "non-hardlinked tree" case correctly.
