[ros-users] rosbag record from launch file

[Jeremy Leibs]

This is because roslaunch does not use your local path.  If you
assumed you were using your local path, it wouldn't necessarily make
sense if you were to launch a node on a remote machine.

As present I believe your bagfiles are most likely ending up in ~/.ros

As Dan suggests, you should generally specify an absolute path for
your bag.  In rosbag the option is now -o or -O (not -F).
