Yes, step was run from /usr/src. I just failed to point that out. I was still in
that directory after the builds completed.

As for the order of installworld and installkernel. I used to run them in the
order you suggest but found that, as I recall, doing the installkernel first
didn't always work when I had the nvidia driver specified in my /etc/src.conf
file. The details are a bit hazy now, but by installing world first the nvidia
driver was successfully built from ports during the installkernel step.

Well, as I have said, perhaps I've been incredibly lucky for these past 20+
years that I've been doing it this way as I have had no such incidents. I don't
doubt that there are risks, just updating a system carries some pretty significant
risks.

Guess I sorry I said anything about this...didn't mean to get people riled up.
