This breaks "cp -aH" and "cp -aL". Even setting st_nlink={0,1}
does not help there, from coreutils 9.1:

copy_internal():

[...]
  else if (x->preserve_links
           && !x->hard_link
           && (1 < src_sb.st_nlink
               || (command_line_arg
                   && x->dereference == DEREF_COMMAND_LINE_ARGUMENTS)
               || x->dereference == DEREF_ALWAYS))
    {
      earlier_file = remember_copied (dst_relname,
                                      src_sb.st_ino, src_sb.st_dev);
    }

Thanks,

Mathieu
