You mean "before_exec", rigth? :)

Yes, it's the solution :)

AFAIK setsid is not 100% valid to daemonize a process because:

- It doesn't handle the exit return code of the process execution (it just 
returns 0 even if the process returns 1 at startup).

- It remains writting in the current stdout (the terminal in which you run 
"setsid program_name".
