Solution 1:

Try pasting LSB comments in your /etc/init.d/panasoniclpd-init :

### BEGIN INIT INFO
# Provides:          panasoniclpd-init
# Required-Start:    $syslog 
# Required-Stop:     $syslog 
# Should-Start:      panasoniclpd-init
# Should-Stop:       panasoniclpd-init
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: panasoniclpd-init - panasonic
# Description: This daemon for panasonic
### END INIT INFO

At the start, just after the shebang (#!/bin/sh) line.
