Yes, go read the FAQ at http://www.macbsd.com/macbsd/macbsd-docs/.
Ok, it's because you booted the system in single-user mode.  Normally
a system is operational in multi-user mode, which, in case of mac68k,
is configurable in the Booter's [Options][Boot] dialog box.

Did you install etc121?  I think that's the reason.
