I get that the "o" in "--ro" is supposed to stand for "only", but this feels clunky to me (especially if there's also a "--rox", which is self-contradictory). I like my long options to be, well, long (complete English words), and backed up by short options. In this case, I'd propose having "-r, --read, -w, --write, -x, --exec", and allowing the short options to be combined as flags (i.e. -rwx).
