I was asking how I make/control a lock file when the rpm provides a 
binary run module and the man page does not mention a lock file.  How do 
I find out if there is a lock file?  How do I get one working?  Do I 
necessarily need one, perhaps the binary determines its running status 
before trying to start a second copy?  Actually, I think I discovered 
that miredo will not start a second copy, oops.

Miredo comes from sourceforge.  Fortunately, I do not have to create it.....
