Indeed: (defun vc-rcs-find-file-hook () ;; If the file is locked by some other user, make ;; the buffer read-only. Like this, even root ;; cannot modify a file that someone else has locked.

No, it actually checks the RCS status. It doesn't need the `rcs` executable for that, instead it parses the RCS file. Stefan
