# Note: ln -s /dev/null /dev/raw1394 is to prevent error on python's
#       cv2 during import: "libdc1394 error: Failed to initialize libdc1394"
#       So, if you want to run another command, just update your CMD to start
#       with this script, followed by whatever you want. (Not cute, but works)
#
CMD sh -c 'ln -s /dev/null /dev/raw1394'; npm start
