Thats what I've tried, but it did not work. Maybe it's because I want to
start something like su -c '/path/to/skript $parameter1 $parameter2' user
I don't understand the syntax of spawn os.spawnlp(os.P_NOWAIT, "/path/to
script", "the script again?", "the args for the script?")

Thats what I've used in the Shellscript, but I haven't realized how to use
it in thy python script, thanks! :)
