### BEGIN INIT INFO

# Provides: udev

# 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.
