actually, this is very easy:

(defmethod hard-link :around (from to)
  (if (symbolic-link-p to)
      (symbolic-link from (resolve-symbolic-link to))
      (call-next-method)))

i.e., when the target is a symlink, you symlink to its target.

think of a symlink as if it had no inode (like it is on a real FS),
i.e., just a special dirent pointing to the target.
Then the hardlink of a symlink is another symlink pointing to the same
place, since the nature of hardlink is to create a file which is
indistinguishable from the target.
