Good afternoon,

I'm a new user of ROS. I developped an application on Raspberry Pi 2 Model B with ROS Indigo and Raspian Wheezy. I have to launch this application on the startup of my Raspberry. So I designed a script which is executed on the startup of the Raspberry Pi to launch roscore (in the first phase). Indeed, I linked it with success. Here is my script :

#!/bin/bash
### BEGIN INIT INFO
# Provides:          servoblaster
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Init servoblaster + Run adas application
# Description:       Run a command which must be executed to run a PWM signal
#                    Define sources for ROS and launch the adas application, thanks to roslaunch
### END INIT INFO

# -*- coding: utf-8 -*-
# Debian init.d script for servoblaster


 case "$1" in
  start)
    touch /tmp/test_start
    /home/pi/PiBits/ServoBlaster/user/servod

    export ROS_ROOT=/home/pi/ros_from_sources/src/ros/rosbuild
    export ROS_MASTER_URI=http://localhost:11311
    export PYTHONPATH=/home/pi/ros_from_sources/devel/lib/python2.7/dist-packages:/opt/ros/indigo/lib/python2.7/dist-packages

    export ROS_ETC_DIR=/home/pi/ros_from_sources/devel/etc/ros
    export ROS_DISTRO=indigo
    export LC_ALL=C

    source /opt/ros/indigo/setup.bash
    source /home/pi/ros_from_sources/devel/setup.bash
    env | grep ROS

    roscore

    touch /tmp/test_stop
#    sudo ./home/pi/PiBits/ServoBlaster/user/servod
  ;;
  reload|force-reload)
    touch /tmp/test_reload
#    sudo ./home/pi/PiBits/ServoBlaster/user/servod
  ;;
  restart)
    touch /tmp/test_restart
    /home/pi/PiBits/ServoBlaster/user/servod
  ;;
  status)
    touch /tmp/test_status
#    sudo ./home/pi/PiBits/ServoBlaster/user/servod
    ;;
  *)
    echo "Usage: /etc/init.d/$NAME {start|stop|reload|restart|force-reload|status}" >&2
    exit 2
  ;;
esac

exit 0

But an error appeared and I didn't manage to solve it. Here is the log error :
