I believe coreutils-6.3 works around that Darwin bug reliably.

This is the hardlink bug he's talking about:
  http://lists.gnu.org/archive/html/bug-coreutils/2006-09/msg00366.html

That Darwin-7.9.0/NFS/hardlink bug is a nasty one.
I'm not convinced it's worth working around, since Darwin-7.9.0 is
so buggy, and the bug seems to appear only on another type of system,
when using an NFS mounted HFS+ partition.

The problem is that even if I write the work-around code, I'm not
confident it'll ever be exercised (how many people use such a buggy OS
as an NFS server?  Then, given that small number, how many also use the
GNU coreutils?), and although the proposed work-around sounds trivial
(upon EIO, rename and repeat the unlink attempt), it's more than a few
lines, and it is code that would potentially run on any system, so it
can't be ifdef'd.

Thanks for doing that.
