There's a bit more to it than that I think. 

As I understand it, local scripts that contain a "# PROVIDE" line are
integrated into rcorder, local scripts  that don't have that line, but
end in .sh, are executed from  /etc/rc.d/localpkg in the old-style.
AFAIK local scripts that have neither are ignored.

So in short, a user script that simply responds to start/stop needs to
go /usr/local/etc/rc.d/, and it does need a .sh extension.
