For the parameter, I have done a new script:

#!/bin/bash
cd /usr/lib/rt-exec
if [ ! $0 ]
    then ./start -s $0 &
    else ./start &
fi

It seam to work. When runing "/usr/sbin/rt_exec sched_1". the script will run "./start -s sched_1"
But now, the srcipt don't show the output of the command in the console, and I don't know how it is possible to modify the script to do that. Any clue someone?

I know at it work because mon is working, but it will be really cool to have start's output in the console, it is some interesting output.

Best,
Dominique
