Bug#100363: modconf should behave better with already inserted modules
While going through the boot-floppies install I had to rm -rf /target/ because
I wanted to try installing the base system again. When I got to the
'configure device drivers' section modconf was clever enough to see that I
alreay has 3c509 inserted. There was a '+' next to it and when I selected it
it asked me if I wasnted to remove the modules, I said 'no' and left.
Problem is that it left me with a blank /etc/modules. That isn't what I would
have expected. I think it would be better if in that situation it added 3c509
