That's what /etc/inittab does. I'm using it for both side of my
sensor/controller project:
dd:2345:respawn:/usr/local/bin/displayd 2>/dev/null
sp:2345:respawn:/usr/local/bin/sensorproc 2>/dev/null
The first two-letter indicator is just an identifier, the path names are
specified, and "respawn" means to restart it when it's killed. "init Q"
will cause /etc/inittab to be re-read.
It works very well for me.
