-==========================
-Cold/Hotplugging with Udev
-==========================
-Version 1.1.7
-written by Tobias Powalowski <tpowa at archlinux.org>
-
----------------
-* Requirements:
----------------
-- recommended kernel >=2.6.23 for this udev to work properly.
-- No more DevFS device paths! If you have them, update /etc/fstab:
- /dev/discs/... etc. has been deprecated in favor of the old style:
- /dev/discs/disc0/part1 -> /dev/hda1
- /dev/discs/disc1/part2 -> /dev/hdb2
-- /etc/modprobe.conf should be cleaned from old install entries (see below).
-
----------------
-* Udev Changes:
----------------
-- The syntax of udev rules has been changed in >=098 release, please update your rules.
- --- Snip Changelog Udev 098
- Renaming of some key names:
- BUS -> SUBSYSTEMS
- ID -> KERNELS
- SYSFS -> ATTRS
- DRIVER -> DRIVERS
- ATTR{file}="value" can be used now, to write to a sysfs file of the
- event device. Instead of:
- ..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
- we now can do:
- ..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
- All the PHYSDEV* keys are deprecated and will be removed from a
- future kernel:
- PHYDEVPATH - is the path of a parent device and should not be
- needed at all.
- PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
- matched with SUBSYSTEMS==
- PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
- Newer kernels will have DRIVER in the environment,
- for older kernels udev puts in. Class device will
- no longer carry this property of a parent and
- DRIVERS== can be used to match such a parent value.
- Note that ENV{DRIVER} is only available for a few bus devices, where
- the driver is already bound at device event time. On coldplug, the
- events for a lot devices are already bound to a driver, and they will have
- that value set. But on hotplug, at the time the kernel creates the device,
- it can't know what driver may claim the device after that, therefore
- in most cases it will be empty.
- --- snap Changelog Udev 098
-- optional udev >= 099 Persistent rules generator for network and cd/dvd devices was added.
-- default udev rules are installed to /lib/udev/rules.d/, they can be overriden by placing
- own rules files to /etc/udev/rules.d/ .
-
----------------
-* How it works:
----------------
-- Udev replaces the functionality of hotplug and hwdetect scripts.
-- Udev does autoloading of modules and coldplugging.
-- Udev loads the modules simultaneously, which is much faster,
- but can cause some troubles with multiple network/sound/etc devices
- (see below).
-- To reload your rules please use '/sbin/udevadm trigger'.
-
-======================
-* Autoloading modules:
-======================
-
--------------------------------------------------------------------------
-* Module autoloading is controlled by MOD_AUTOLOAD="" in /etc/rc.conf
--------------------------------------------------------------------------
-MOD_AUTOLOAD="yes" in /etc/rc.conf is necessary:
-- if you want module autodetection
-- if you want modules be loaded by udev (hotplugging and coldplugging)
-
-MOD_AUTOLOAD="no" is necessary:
-- if you want to load modules strictly using 'modprobe <module>'
-- if you want to load only the modules listed in the MODULES=() array
- in /etc/rc.conf
-
----------------
-* Blacklisting:
----------------
-- means udev will never try to load the module, even if MOD_AUTOLOAD="yes"
- is set.
-
-You can do this in 2 ways:
-- MOD_BLACKLIST=(moduleA moduleB)
-- MODULES=(!moduleA !moduleB)
-
-Both entries mean the same thing to udev. MOD_BLACKLIST was used by hwdetect.
-hwdetect does not understand the MODULES= syntax, but it doesn't have to -- it
-is only used in mkinitrd now.
-
-==================================
-* Boot parameter: load_modules=off
-==================================
-
-- No modules are loaded during boot using udev autoloading or the MODULES array
-- Useful for repairing your system if something goes wrong during udev startup
- and/or during loading modules
-
-==================================
-* Boot parameter: disablemodules=
-==================================
-
-- list modules there that shouldn't be loaded by udev
-- Syntax: disablemodules=module1,module2,module3,...
-- Useful for repairing your system if something goes wrong during udev startup
- and/or during loading modules and you know the module that causes the trouble.
-
-========================================
-* Persistent CD/DVD symlinks (optional):
-========================================
-
-- To enable this feature copy in /etc/udev/rules.d
- 75-cd-aliases-generator.rules.optional
- to 75-cd-aliases-generator.rules
-- To get the same device name for CD/DVD symlinks each time you boot,
- a rule will be generated during bootup or by executing '/sbin/udevadm trigger'.
-- Examples: dvd, cdrom ,cdrw etc.
-- If you want to change those links,
- modify '/etc/udev/rules.d/70-peristent-cd.rules' to your needs.
-
-Known issues:
-The symlink name is then bound to the hardware pci adress,
-if you change your CD/DVD device, you have to check the
-/etc/udev/rules.d/70-peristent-cd.rules file for correctness.
-
-======================================
-* Persistent Network names (optional):
-======================================
-
-- To enable this feature copy in /etc/udev/rules.d
- 75-persistent-net-generator.rules.optional
- to 75-persistent-net-generator.rules
-- To get the same network device name each time you boot,
- a rule will be generated during bootup or by executing '/sbin/udevadm trigger'.
-- Examples: eth0, eth1, wlan0 etc.
-- If you want to change those names,
- modify '/etc/udev/rules.d/70-peristent-net.rules' to your needs.
-- NAME= determines the name of your network card. Use these names in your
- network configuration in rc.conf as well.
-
-Known issues:
-The interface name is then bound to the hardware mac adress,
-if you change your network card, you have to check the
-/etc/udev/rules.d/70-peristent-net.rules file for correctness.
-
-====================================
-* Known Problems Hardware:
-====================================
-
-- BusLogic devices are broken and will cause a freeze during startup
-Solution:
-This is a kernel bug and no fix has been provided yet.
-
-- PCMCIA Card readers are not treated as removabel devices.
-Solution:
-To get access to them with hal's pmount backend add them to /etc/pmount.allow
-
-====================================
-* Known Problems MOD_AUTOLOAD="yes":
-====================================
-
------------------------------------------------------------------------------
-* Sound is not working or modules (eg. parport) are not loaded automatically:
------------------------------------------------------------------------------
-Solution:
-- Do you have a clean /etc/modprobe.conf?
- - A clean /etc/modprobe.conf is empty. The stock modprobe.conf file
- contains nothing
-- alsaconf can write output to modprobe.conf. Please keep that in mind.
-
----------------------------------------------
-* Devices get mixed up eg. Network/Soundcards
----------------------------------------------
-- Because udev loads all the modules at once, sometimes devices are initialized
- in different orders (eg. network cards switch eth0 and eth1, sound cards
- the same)
-
-Solution:
-- Load them in MODULES=() array in the order you need them
-- eg: MODULES=(moduleA moduleB)
-
-Second solution for network:
-- The "proper" way to configure net interfaces to hold static names within
- udev rules. Add lines like these to a custom rules file such as
- /etc/udev/rules.d/01-network.rules:
- SUBSYSTEM=="net", SYSFS{address}=="aa:bb:cc:dd:ee:ff", NAME="lan0"
- SUBSYSTEM=="net", SYSFS{address}=="ff:ee:dd:cc:bb:aa", NAME="wlan0"
-
-- To get the right mac address use this command:
- udevinfo -a -p /sys/class/net/<yourdevice>
-- Make sure you use lower-case hex values in your udev rules.
-- NAME= determines the name of your network card. Use these names in your
- network configuration in rc.conf as well.
-
-Third solution for network:
-- check Persistent Network part
-
------------------------------------
-* Network 8139too & 8139cp problem:
------------------------------------
-- Both modules have the same kernel entry, which can cause problems.
-Solution:
-- Enter the one you need in MODULES=() and blacklist the other one
-- eg: MODULES=(!8139cp 8139too)
-- The example tells udev to ignore 8139cp module and load 8139too afterwards.
-
---------------------------------------------------------
-* You need a special loading order to get devices going:
---------------------------------------------------------
-- Kernel loads modules in wrong order.
-Solution:
-- Load them in the correct order in MODULES=()
-
------------------------------
-* Module is not autodetected:
------------------------------
-- If your device does not provide a modalias in /sys it cannot be autodetected.
-- If modalias is not combined to a kernel module it cannot be autodetected.
-Known modules that are not autodetected:
-- SCSI CONTROLLER:
- scsi_transport_sas ultrastor qlogicfas eata BusLogic pas16 wd7000 sym53c416
- g_NCR5380_mmio fdomain u14-34f dtc initio in2000 imm t128 aha1542 aha152x
- atp870u g_NCR5380 NCR53c406a qlogicfas408 megaraid_mm advansys
-- NETWORK CARDS:
- hp ne de4x5 wd cs89x0 eepro smc9194 seeq8005 ni52 ni65 ac3200 smc-ultra
- at1700 hp-plus depca eexpress 82596 de600 eth16i de620 lance ewrk3 e2100
- lp486e 3c501 3c503 3c505 3c507 3c509 3c515 myri10ge
-Solution:
-- Enter the one you need in MODULES=()
-
-=======================================
-* Known Problems with MOD_AUTOLOAD="no"
-=======================================
-
------------------------------------------------------------------
-* Modules are not loaded anymore during coldplug or hotplug event
------------------------------------------------------------------
-- Udev is usually responsible for this, but the MOD_AUTOLOAD switch will
- now disable it. If you want automatic hot/cold-plugging, turn on
- MOD_AUTOLOAD. Otherwise you will have to load all your modules manually,
- either with /sbin/modprobe or entries in the MODULES=() array.
-Solution:
-- For bootup (coldplug) enter this in rc.conf: MODULES=(moduleA moduleB)
-- After bootup (hotplug) use this: modprobe <moduleA>

-* Known problems for custom kernel users:

-* Udev doesn't start at all:
