Brian, there's enough significant changes to a freebsd install that I think you'll find it easier to complete those steps manually. I'm sending you my draft notes.
There are file location changes, and command changes.
for example:
bash-2.05b# pw groupadd service0
bash-2.05b# pw useradd service0 -d /home/service0 -g service0
bash-2.05b# pw usermod service0 -G web
performance tuning is significantly different.
I'm waiting for cvs access so the notes can be added to the docs.
