Sorry, sent that without any real thought.

To get this far, the bootloader has managed to mount the root file system.
In order for the system to come up the rest of the way, certain things must
be located on the root partition, including /etc - without it, init is not
able to call /etc/rc, which in turn means that /etc/fstab, all your
/etc/rc.* scripts etc are not available.  The login_getclass error above
occurs because init cannot find /etc/login.conf.

So, your root file system should include /etc, /bin, /sbin, /dev, so that 
things like /sbin/mount, and all your devices etc are available to complete
the startup procedure.

init will quite happily call /etc/rc once you have manually mounted all your
local file systems, because it can now find everything it needs.

If you have previously managed to get it running like this in the past, I am
sure I don't know how ;-)
