CATEGORY: UDEV

TITLE: Introduction

T: UDEV seems to replace DEVFS. Actualy, DEVFS is not really supported anymore.

TITLE: Requirements

T: Kernel 2.6 with udev support.

TITLE: Installation

T: Just call

C: apt-get install udev gnome-volume-manager

TITLE: Configuration

T: Add sysfs in fstab

C: none /sys sysfs defaults 0 0

T: and mount it

C: mount /sys

TITLE: Device configuration

T: Each device seems to be identified by a model and vendor. Here how to find out these values.

T: Plug in your USB device and get the device name:

C: tail -n 20 /var/log/message
  
T: You should find sda or sdb or something like this.

T: In the next steps, replace sda with what you have found before.

T: Call 

C: udevinfo -q path -n /dev/sda

C: udevinfo -a -p /sys/block/sda | grep BUS
C: udevinfo -a -p /sys/block/sda | grep model
C: udevinfo -a -p /sys/block/sda | grep vendor

T: You should find something like:
  
C: BUS="scsi"
C: SYSFS{model}="..."
C: SYSFS{vendor}="Apacer  "

T: Add and entry in /etc/udev/udev.rules:

C: BUS="scsi", SYSFS{vendor}="Apacer  ", NAME="apacer%n", SYMLINK="%k"

T: Create directory for script to be called (replace apacer with your vendor name)

C: mkdir /etc/dev.d/apacer-1

T: and copy the following script in /etc/dev.d/apacer-1/mount

C: #!/bin/sh

C: if [ "$ACTION" == "add" ]
C: then
C:   USER=`ps -elf | grep x-session-manager | cut -d " " -f 3 | head -n 1`
C:   su -c "mount /media/palmint-1" $USER
C: fi

T: Create mountpoint:

C:   mkdir /media/apacer-1

T: add following line in your /etc/fstab:

C: /dev/apacer-1   /media/apacer-1    auto    user,noauto,noatime,sync,defaults

T: Hal-volume-manager can show a lot informations about your hardware, but I couldn't find a package providing it.
