Yes, of course, I meant sysinst. :)

Well, that all sounds like a lot of work. I have a few other ideas as
well. One would be to try what you did and just install from a NetBSD
CD manually. I found some notes on that at .
I don't know if I can get everything to work that way but if it works
it is probably less work than the way you suggest.

Yes. I have grub2 in place already. That part should be alright.
