} so do I need to configure things specially?
} Let me explain:
} I have:
} sd0a : boot
} sd0b : swap
} sd0c : "disk"
} sd0d : /
} 
} I run installboot onto rds0a (although I think it is similar to rsd0c I 
} suppose, being the first)
} 
} the kernel "boots" but then stops with:
} 
} warning: no /dev/console
} exec /sbin/error 2
} init: trying /sbin/oinit

     At this point, the kernel is loaded and running.

} and a load of other errors up to a panic.
} 
} Is it that now the kernel is trying to boot from "sd0a" as root, while I 
} want it to use sd0d ?

     It's trying to find /sbin/init, but can't.  It defaults to
using the filesystem from which it was loaded as the root filesystem.

} How do I achieve this? you mention configure root. How?

     You build a kernel, or you do boot -a and tell it where the
root filesystem is.  To build a kernel, see:
http://www.netbsd.org/docs/guide/en/chap-tuning.html#tuning-kernel .
