Here's a dirty manual way to confirm it. I just chose directories that
I know are on different volumes, but I also confirmed it works with a loopback
filesystem created with something like losetup. This worked, i.e. showed me 
different
free space, with emacs -Q on a clean build of 
c1356d3a05a789555c327dd4cb0f444fdf7be205


;;doesn't matter; just use an existing dir
(setq ld-target "~")

;;two dirs on different volumes
(setq ld-working-dirs '("/" "~/emacs/"))


(require 'ls-lisp)
;;make sure to use the ls-lisp functionality
(setq ls-lisp-use-insert-directory-program nil)


;;shows the list-directory output for all working dirs
(defun insert-ld-bug ()
  (dolist (ld-working-dir ld-working-dirs)
    (let ((default-directory ld-working-dir))
      (list-directory ld-target t)
      (insert-buffer-substring "*Directory*")
      (insert "=====\n\n\n"))))

(with-current-buffer-window "ld-bug" nil nil
  (insert-ld-bug))
