# System startup script for the dvb card driver

### BEGIN INIT INFO
# Provides: dvb
# Required-Start:
# Required-Stop:
# Default-Start:  3 5
# Default-Stop:   0 1 2 6
# Short-Description: (re)loads drivers for DVB cards.
# Description: This script is mostly useless nowadays as drivers
#	are loaded automatically. You may configure vdr to use it
#	to reload drivers in case vdr crashes though. See
#	/etc/sysconfig/vdr
