The ones with the dot prefix are (typically) read/write mountpoints; the
other ones are (typically) "normal" mountpoints. See

If your client is running with dynroot, such mountpoints are created
automatically, so it's more than just a convention these days.

That cell probably has a root.cell RW volume that has some directories
(namely, 'bin' and 'share') that haven't been released to the RO.
