A simple function for init.d to have a roslaunch run at startup at tty8 and tty9

ROS init.d

start_ros () {
    source /opt/ros/setup.sh

    roscore <>/dev/tty8 2>/dev/tty8 & disown
    until rostopic list ; do sleep 1; done
    roslaunch YOUR_PACKAGE YOUR_LAUNCH_FILE.launch <> /dev/tty9 2>/dev/tty9 & disown
}

stop_ros () {
    source /opt/ros/setup.sh

    #killall nodes
    for i in $( rosnode list ); do
    rosnode kill $i;
    done

    #stop roscore
    killall roscore
}
