>>Surely hard links couldn't point to directories, so it was only about

they could, but (at least by 5th eidtion) it was restricted to the super-user.
in fact, that was how directory rename was implemented, by setuid mv using
link and unlink.  races?  argument checking?  ``values of [beta] will give rise to dom!''.
the . and .. names were actual links in the directory, put there by the mkdir command.
the rmdir command did the 3 unlinks (for ., .., and the name itself).
