Eivind,
I have been playing with your package for a little while now. I
like it so far and was waiting to see if you had anything else in
the way of enhancements for it prior to commenting (as you've only
released 0.2 thus far). You're point about the base install didn't
bother me as I was using it for diskless installations.
I like both of your ideas, adapting it for ports and for sysinstall.
Have you received any feedback? Are there any known bugs or
limitations in the current revision that might preclude
experimentation with doing this now?
