# 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
