I see two votes in a week, enough for me to use it, will ammend.

I rather have someone with NetBSD verify and then make that change.

It does and I tried to use the same name but if one does a git mv of a file
git adds that old file name and path to a temporary .gitignore requiring you
to use git add -f on that file. It does this because if you insist you loose
the history of the file after the move. Its also why I changed the name of
this modified init.

If you don't want to keep the history I can move forward with a mv but the
history will be lost. I did explain this in the commit log so hope is that
anyone with the same WTF reaction would understand why this as done, I know
I said WTF as well, I tried to avoid this at all costs, let me know if anyone
thinks of a better way.

What I mean by keeping the history is you can do git log --follow on the
script after the move.

OK, will ammend.
