AFAIT there's no way of making tar preserve hard links (although it
preserves symlinks by default anyway). Of course, they could think
preserving hard links so trivially obvious and simple that it's
not worth mentioning in the man page. I'm too lazy to actually try
it to find out.
 
HTH, FWIW, etc.

Cheers,
