'mv' (fileutils-4.1) cannot rename hard link files.

Hi,
I use 'mv' of fileutils-4.1 on Debian GNU/Linux woody.
I realized that 'mv' cannot rename hard link files.


 % mv --version

 ./tmp:

 2232058 -rw-r--r--    1 yokota   yokota          0 Aug 14 09:37 B

and,

 % mv -f A B tmp 
 mv: cannot create hard link `tmp/B' to `tmp/A': File exists
