#! /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

# Note on script names:
# http://www.linuxbase.org/spec/refspecs/LSB_1.2.0/gLSB/scrptnames.html
# A registry has been set up to manage the init script namespace.
# http://www.lanana.org/
# Please use the names already registered or register one or use a
# vendor prefix.
