#! /bin/sh
#
# Author: Rolf Eike Beer <eike-hotplug@sf-tec.de>
#   derived from original RedHat udev init script
#   based on the SuSE 9.0 template (c) 1995-2002 SuSE Linux AG
#
# /etc/init.d/udev
#   and its symbolic link
# /(usr/)sbin/rcudev
#
# System startup script for udev
#
# LSB compatible service control script; see http://www.linuxbase.org/spec/

### BEGIN INIT INFO
# Provides:          udev
# Required-Start:    
# Required-Stop:     
# Default-Start:     1 2 3 5
# Default-Stop:      0 6
# Short-Description: manage user-space device nodes in /udev
# Description:       Start udev to create the device files for all
#		     devices already present in system when script is
#		     called. All other devices files will be automatically
#		     created when udev is called via /sbin/hotplug.
#		     Requires at least a kernel 2.6 to work properly.
### END INIT INFO

# A registry has been set up to manage the init script namespace.

# Please use the names already registered or register one or use a
# vendor prefix.
