No, not a tarfile limitation, there are hard links in the tarfile test
code.  The exception in duplicity is "Hard links not supported yet" if
you try to back up a hard link, kind of implying work to be done.

I'll have to study up on how hard links are handled before commenting
further.  As I recall, there's some really odd logic in handling files
with multiple hard links coming to them.
