foolish me

I was working on installing netBSD 2.0
and my first thing was to install bash
but... I told "chsh" that my shell was in "/usr/bin/bash" when it was
really "/usr/pkg/bin/bash"
so... I dont have any other accounts yet
and I already took forever to download, untar and install pkgsrc, then
finally bash

is there anyway I can boot the qube in single user mode ?

any help or other ideas would be great
