You cannot HardLink directories, "." and ".."'s are already hardlinks to the current and parent directories respectively. The root directories ".." entry points to "." as well. Programs such as find(1) use the knowledge that "." and ".." are the only two hardlinks, and therefore know that after they have processed (number of links + 2) subdirectories that they have found them all, and they nolonger have to stat(1) every file in the directory to see if it's a subdirectory.
