Hmm, that's tricky.

So I guess the real problem here is that init does not know enough to  
start a login prompt on the console. This has irritated me for a while  
actually. Maybe that should be fixed? The "console" entry, which would  
always automatically work, in /etc/ttys is marked off, which  
apparently happened in the runup to 4.0. It might be time to revisit  
that.
