You have to mount them first.
This is covered in the FAQ.

Quoting the Fine Manual:

     If the security level is initially nonzero, then init leaves it
     unchanged.  Otherwise, init raises the level to 1 before going multi-user
     for the first time.  Since the level cannot be reduced, it will be at
     least 1 for subsequent operation, even on return to single-user.  If a
     level higher than 1 is desired while running multi-user, it can be set
     before going multi-user, e.g., by the startup script rc(8), using
     sysctl(8) to set the ``kern.securelevel'' variable to the required secu-
     rity level.
