Mind if I ask why this is needed?
This is a real question: why can't the machine just be brought up at
the right securelevel and be done with it? If it comes multiuser up
at the wrong secure level isn't that a security problem in and of
itself?
Or is there something that needs to be done during boot up that can't
be done at the intended securelevel? [This would seem to indicate a
flawed security model or flawed hardware.]
