Not absolutely needed, but it creates all the directories and files you
need correctly, so it's a good start.

…then modify it as described and then run setup.exe again and let it
"update" your installation.  If you had any services running you'll also
need to run their initialization scripts again.

Not unless you have scripts that use the Windows path someplace.  You'll
find out soon enough, I think.

It was this one:


You need a slight modification of the sed script however due to a more
recent format change of installed.db:

sed -re 's/^(.+) .+ ([01])$/\1 \1-0-0.tar.bz \2/' installed.db.old > /etc/setup/installed.db
