What exactly is not working? Are you saying you are dropping back to
single-user mode from multi-user? That does not work with
FreeBSD. init(8) says,
Since the level can not be reduced, it will be at
least 1 for subsequent operation, even on return to single-user.
Note however, this behavior does vary between *BSDs. By default, when
you bring OpenBSD to single-user from multi-user, the securelevel
drops.

Right. How else were you trying to boot to single-user mode? Were you
dropping from multi-user?
