The reason why I don't like the default to be "preserve the inode
ownership" is because it's *not* just like link(2).  If it were just
like link(2), the inode number would also be preserved.  If the inode
number is changing, then it arguably is ***much*** more like a copy.
And a copy operation also has many useful properties.
