Not quite. As mentioned a little earlier, you need to add "through this mount." It's a state of the mount, not the kernel image. It's a good point, though, that we shouldn't kid ourselves that having a mount in read-only state means the filesystem is read-only. In the cases where it does, though, it's an especially useful state.
