-udev 169
-========
-Bugfixes.
-
-We require at least Linux kernel 2.6.32 now. Some platforms might
-require a later kernel that supports accept4() and similar, or
-need to backport the trivial syscall wiring to the older kernels.
-
-The hid2hci tool moved to the bluez package and was removed.
-
-Many of the extras can be --enable/--disabled at ./configure
-time. The --disable-extras option was removed. Some extras have
-been disabled by default. The current options and their defaults
-can be checked with './configure --help'.
-
-udev 168
-========
-Bugfixes.
-
-Udev logs a warning now if /run is not writable at udevd
-startup. It will still fall back to /dev/.udev, but this is
-now considered a bug.
-
-The running udev daemon can now cleanly shut down with:
- udevadm control --exit
-
-Udev in initramfs should clean the state of the udev database
-with: udevadm info --cleanup-db which will remove all state left
-behind from events/rules in initramfs. If initramfs uses
---cleanup-db and device-mapper/LVM, the rules in initramfs need
-to add OPTIONS+="db_persist" for all dm devices. This will
-prevent removal of the udev database for these devices.
-
-Spawned programs by PROGRAM/IMPORT/RUN now have a hard timeout of
-120 seconds per process. If that timeout is reached the spawned
-process will be killed. The event timeout can be overwritten with
-udev rules.
-
-If systemd is used, udev gets now activated by netlink data.
-Systemd will bind the netlink socket which will buffer all data.
-If needed, such setup allows a seemless update of the udev daemon,
-where no event can be lost during a udevd update/restart.
-Packages need to make sure to: systemctl stop udev.socket udev.service
-or 'mask' udev.service during the upgrade to prevent any unwanted
-auto-spawning of udevd.
-This version of udev conflicts with systemd version below 25. The
-unchanged service files will not wirk correctly.
-
-udev 167
-========
-Bugfixes.
-
-The udev runtime data moved from /dev/.udev/ to /run/udev/. The
-/run mountpoint is supposed to be a tmpfs mounted during early boot,
-available and writable to for all tools at any time during bootup,
-it replaces /var/run/, which should become a symlink some day.
-
-If /run does not exist, or is not writable, udev will fall back using
-/dev/.udev/.
-
-On systemd systems with initramfs and LVM used, packagers must
-make sure, that the systemd and initramfs versions match. The initramfs
-needs to create the /run mountpoint for udev to store the data, and
-mount this tmpfs to /run in the rootfs, so the that the udev database
-is preserved for the udev version started in the rootfs.
-
-The command 'udevadm info --convert-db' is gone. The udev daemon
-itself, at startup, converts any old database version if necessary.
-
-The systemd services files have been reorganized. The udev control
-socket is bound by systemd and passed to the started udev daemon.
-The udev-settle.service is no longer active by default. Services which
-can not handle hotplug setups properly need to actively pull it in, to
-act like a barrier. Alternatively the settle service can be unconditionally
-'systemctl'enabled, and act like a barrier for basic.target.
-
-The fstab_import callout is no longer built or installed. Udev
-should not be used to mount, does not watch changes to fstab, and
-should not mirror fstab values in the udev database.
-
-udev 166
-========
-Bugfixes.
-
-New and updated keymaps.
-
-udev 165
-========
-Bugfixes.
-
-The udev database has changed, After installation of a new udev
-version, 'udevadm info --convert-db' should be called, to let the new
-udev/libudev version read the already stored data.
-
-udevadm now supports quoting of property values, and prefixing of
-key names:
- $ udevadm info --export --export-prefix=MY_ --query=property -n sda
- MY_MAJOR='259'
- MY_MINOR='0'
- MY_DEVNAME='/dev/sda'
- MY_DEVTYPE='disk'
- ...
-
-libudev now supports:
- udev_device_get_is_initialized()
- udev_enumerate_add_match_is_initialized()
-to be able to skip devices the kernel has created , but udev has
-not already handled.
-
-libudev now supports:
- udev_device_get_usec_since_initialized()
-to retrieve the "age" of a udev device record.
-
-GUdev supports a more generic GUdevEnumerator class, udev TAG
-handling, device initialization and timestamp now.
-
-The counterpart of /sys/dev/{char,block}/$major:$minor,
-/dev/{char,block}/$major:$minor symlinks are now unconditionally
-created, even when no rule files exist.
-
-New and updated keymaps.

-
-Persistent network naming rules are disabled inside of Qemu/KVM now.

-Udev gets unconditionally enabled on systemd installations now. There
-is no longer the need to to run 'systemctl enable udev.service'.

-
-udev 158
-========
-Bugfixes.
-
-All distribution specific rules are removed from the udev source tree,
-most of them are no longer needed. The Gentoo rules which allow to support
-older kernel versions, which are not covered by the default rules anymore
-has moved to rules/misc/30-kernel-compat.rules.
-
-udev 157
-========
-Bugfixes.
-
-The option --debug-trace and the environemnt variable UDEVD_MAX_CHILDS=
-was removed from udevd.
-
-Udevd now checks the kernel commandline for the following variables:
- udev.log-priority=<syslog priority>
- udev.children-max=<maximum number of workers>
- udev.exec-delay=<seconds to delay the execution of RUN=>
-to help debuging coldplug setups where the loading of a kernel
-module crashes the system.
-
-The subdirectory in the source tree rules/packages has been renamed to
-rules/arch, anc contains only architecture specific rules now.
-
-udev 156
-========
-Bugfixes.
-
-udev 155
-========
-Bugfixes.
-
-Now the udev daemon itself, does on startup:
- - copy the content of /lib/udev/devices to /dev
- - create the standard symlinks like /dev/std{in,out,err},
- /dev/core, /dev/fd, ...
- - use static node information provided by kernel modules
- and creates these nodes to allow module on-demand loading
- - possibly apply permissions to all ststic nodes from udev
- rules which are annotated to match a static node
-
-The default mode for a device node is 0600 now to match the kernel
-created devtmpfs defaults. If GROUP= is specified and no MODE= is
-given the default will be 0660.
-
-udev 154
-========
-Bugfixes.
-
-Udev now gradually starts to pass control over the primary device nodes
-and their names to the kernel, and will in the end only manage the
-permissions of the node, and possibly create additional symlinks.
-As a first step NAME="" will be ignored, and NAME= setings with names
-other than the kernel provided name will result in a logged warning.
-Kernels that don't provide device names, or devtmpfs is not used, will
-still work as they did before, but it is strongly recommended to use
-only the same names for the primary device node as the recent kernel
-provides for all devices.
-
-udev 153
-========
-Fix broken firmware loader search path.
-
-udev 152
-========
-Bugfixes.
-
-"udevadm trigger" defaults to "change" events now instead of "add"
-events. The "udev boot script" might need to add "--action=add" to
-the trigger command if not already there, in case the initial coldplug
-events are expected as "add" events.
-
-The option "all_partitons" was removed from udev. This should not be
-needed for usual hardware. Udev can not safely make assumptions
-about non-existing partition major/minor numbers, and therefore no
-longer provide this unreliable and unsafe option.
-
-The option "ignore_remove" was removed from udev. With devtmpfs
-udev passed control over device nodes to the kernel. This option
-should not be needed, or can not work as advertised. Neither
-udev nor the kernel will remove device nodes which are copied from
-the /lib/udev/devices/ directory.
-
-All "add|change" matches are replaced by "!remove" in the rules and
-in the udev logic. All types of events will update possible symlinks
-and permissions, only "remove" is handled special now.
-
-The modem modeswitch extra was removed and the external usb_modeswitch
-program should be used instead.
-
-New and fixed keymaps.
-
-udev 151
-========
-Bugfixes.
-
-udev 150
-========
-Bugfixes.
-
-Kernels with SYSFS_DEPRECATED=y are not supported since a while. Many users
-depend on the current sysfs layout and the information not available in the
-deprecated layout. All remaining support for the deprecated sysfs layout is
-removed now.
-
-udev 149
-========
-Fix for a possible endless loop in the new input_id program.
-
-udev 148
-========
-Bugfixes.
-
-The option "ignore_device" does no longer exist. There is no way to
-ignore an event, as libudev events can not be suppressed by rules.
-It only prevented RUN keys from being executed, which results in an
-inconsistent behavior in current setups.
-
-BUS=, SYSFS{}=, ID= are long deprecated and should be SUBSYSTEM(S)=,
-ATTR(S){}=, KERNEL(S)=. It will cause a warning once for every rule
-file from now on.
-
-The support for the deprecated IDE devices has been removed from the
-default set of rules. Distros who still care about non-libata drivers
-need to add the rules to the compat rules file.
-
-The ID_CLASS property on input devices has been replaced by the more accurate
-set of flags ID_INPUT_{KEYBOARD,KEY,MOUSE,TOUCHPAD,TABLET,JOYSTICK}. These are
-determined by the new "input_id" prober now. Some devices, such as touchpads,
-can have several classes. So if you previously had custom udev rules which e. g.
-checked for ENV{ID_CLASS}=="kbd", you need to replace this with
-ENV{ID_INPUT_KEYBOARD}=="?*".
-
-udev 147
-========
-Bugfixes.
-
-To support DEVPATH strings larger than the maximum file name length, the
-private udev database format has changed. If some software still reads the
-private files in /dev/.udev/, which it shouldn't, now it's time to fix it.
-Please do not port anything to the new format again, everything in /dev/.udev
-is and always was private to udev, and may and will change any time without
-prior notice.
-
-Multiple devices claiming the same names in /dev are limited to symlinks
-only now. Mixing identical symlink names and node names is not supported.
-This reduces the amount of data in the database significantly.
-
-NAME="%k" causes a warning now. It's is and always was completely superfluous.
-It will break kernel supplied DEVNAMEs and therefore it needs to be removed
-from all rules.
-
-Most NAME= instructions got removed. Kernel 2.6.31 supplies the needed names
-if they are not the default. To support older kernels, the NAME= rules need to
-be added to the compat rules file.
-
-Symlinks to udevadm with the old command names are no longer resolved to
-the udevadm commands.
-
-The udev-acl tool got adopted to changes in ConsoleKit. Version 0.4.1 is
-required now.
-
-The option "last_rule" does no longer exist. Its use breaks too many
-things which expect to be run from independent later rules, and is an idication
-that something needs to be fixed properly instead.
-
-The gudev API is no longer marked as experimental,
-G_UDEV_API_IS_SUBJECT_TO_CHANGE is no longer needed. The gudev introspection
-is enabled by default now. Various projects already depend on introspection
-information to bind dynamic languages to the gudev interfaces.
-
-udev 146
-========
-Bugfixes.
-
-The udevadm trigger "--retry-failed" option, which is replaced since quite
-a while by "--type=failed" is removed.
-
-The failed tracking was not working at all for a few releases. The RUN
-option "ignore_error" is replaced by a "fail_event_on_error" option, and the
-default is not to track any failing RUN executions.
-
-New keymaps, new modem, hid2hci updated.
-
-udev 145
-========
-Fix possible crash in udevd when worker processes are busy, rules are
-changed at the same time, and workers get killed to reload the rules.
-
-udev 144
-========
-Bugfixes.
-
-Properties set with ENV{.FOO}="bar" are marked private by starting the
-name with a '.'. They will not be stored in the database, and not be
-exported with the event.
-
-Firmware files are looked up in:
- /lib/firmware/updates/$(uname -r)
- /lib/firmware/updates
- /lib/firmware/$(uname -r)
- /lib/firmware"
-now.
-
-ATA devices switched the property from ID_BUS=scsi to ID_BUS=ata.
-ata_id, instead of scsi_id, is the default tool now for ATA devices.
-
-udev 143
-========
-Bugfixes.
-
-The configure options have changed because another library needs to be
-installed in a different location. Instead of exec_prefix and udev_prefix,
-libdir, rootlibdir and libexecdir are used. The Details are explained in
-the README file.
-
-Event processes now get re-used after they handled an event. This reduces
-the number of forks and the pressure on the CPU significantly, because
-cloned event processes no longer cause page faults in the main daemon.
-After the events have settled, a few worker processes stay around for
-future events, all others get cleaned up.
-
-To be able to use signalfd(), udev depends on kernel version 2.6.25 now.
-Also inotify support is mandatory now to run udev.
-
-The format of the queue exported by the udev damon has changed. There is
-no longer a /dev/.udev/queue/ directory. The current event queue can be
-accessed with udevadm settle and libudedv.
-
-Libudev does not have the unstable API header anymore. From now on,
-incompatible changes will be handled by bumping the library major version.
-
-To build udev from the git tree gtk-doc is needed now. The tarballs will
-build without it and contain the pre-built documentation. An online copy
-is available here:
- http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/
-
-The tools from the udev-extras repository have been merged into the main
-udev repository. Some of the extras have larger external dependencies, and
-they can be disabled with the configure switch --disable-extras.
-
-udev 142
-========
-Bugfixes.
-
-The program vol_id and the library libvolume_id are removed from the
-repository. Libvolume_id is merged with libblkid from the util-linux-ng
-package. Persistent disk links for label and uuid depend on the
-util-linux-ng version (2.15) of blkid now. Older versions of blkid
-can not be used with udev.
-
-Libudev allows to subscribe to udev events. To prevent unwanted messages
-to be delivered, and waking up the subscribing process, a filter can be
-installed, to drop messages inside a kernel socket filter. The filters
-match on the <subsytem>:<devtype> properties of the device.
- This is part of the ongoing effort to replace HAL, and switch current
-users over to directly use libudev.
- Libudev is still marked as experimental, and its interface might
-eventually change if needed, but no major changes of the currently exported
-interface are expected anymore, and a first stable release should happen
-soon.
-
-A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED
-is not supported since while and udevd will log an error message at
-startup. It should still be able to boot-up, but advanced rules and system
-services which depend on the information not available in the old sysfs
-format will fail to work correctly.
-
-DVB device naming is supplied by the kernel now. In case older kernels
-need to be supported, the old shell script should be added to a compat
-rules file.
-
-udev 141
-========
-Bugfixes.
-
-The processed udev events get send back to the netlink socket. Libudev
-provides access to these events. This is work-in-progress, to replace
-the DeviceKit daemon functionality directly with libudev. There are
-upcoming kernel changes to allow non-root users to subcribe to these
-events.
-
-udev 140
-========
-Bugfixes.
-
-"udevadm settle" now optionally accepts a range of events to wait for,
-instead of waiting for "all" events.
-
-udev 139
-========
-Bugfixes.
-
-The installed watch for block device metadata changes is now removed
-during event hadling, because some (broken) tools may be called from udev
-rules and (wrongly) open the device with write access. After the finished
-event handling the watch is restored.
-
-udev 138
-========
-Bugfixes.
-
-Device nodes can be watched for changes with inotify with OPTIONS="watch".
-If closed after being opened for writing, a "change" uevent will occur.
-/dev/disk/by-{label,uuid}/* symlinks will be automatically updated.
-
-udev 137
-========
-Bugfixes.
-
-The udevadm test command has no longer a --force option, nodes and symlinks
-are always updated with a test run now.
-
-The udevd daemon can be started with --resolve-names=never to avoid all user
-and group lookups (e.g. in cut-down systems) or --resolve-names=late to
-lookup user and groups every time events are handled.
-
-udev 136
-========
-Bugfixes.
-
-We are currently merging the Ubuntu rules in the udev default rules,
-and get one step closer to provide a common Linux /dev setup, regarding
-device names, symlinks, and default device permissions. On udev startup,
-we now expect the following groups to be resolvable to their ids with
-glibc's getgrnam():
- disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem.
-LDAP setups need to make sure, that these groups are always resolvable at
-bootup, with only the rootfs mounted, and without network access available.
-
-Some systems may need to add some new, currently not used groups, or need
-to add some users to new groups, but the cost of this change is minimal,
-compared to the pain the current, rather random, differences between the
-various distributions cause for upstream projects and third-party vendors.
-
-In general, "normal" users who log into a machine should never be a member
-of any such group, but the device-access should be managed by dynamic ACLs,
-which get added and removed for the specific users on login/logout and
-session activity/inactivity. These groups are only provided for custom setups,
-and mainly system services, to allow proper privilege separation.
-A video-streaming daemon uid would be a member of "audio" and "video", to get
-access to the sound and video devices, but no "normal" user should ever belong
-to the "audio" group, because he could listen to the built-in microphone with
-any ssh-session established from the other side of the world.
-
-/dev/serial/by-{id,path}/ now contains links for ttyUSB devices,
-which do not depend on the kernel device name. As usual, unique
-devices - only a single one per product connected, or a real
-USB serial number in the device - are always found with the same
-name in the by-id/ directory.
-Completely identical devices may overwrite their names in by-id/
-and can only be found reliably in the by-path/ directory. Devices
-specified by by-path/ must not change their connection, like the
-USB port number they are plugged in, to keep their name.
-
-To support some advanced features, Linux 2.6.22 is the oldest supported
-version now. The kernel config with enabled SYSFS_DEPRECATED is no longer
-supported. Older kernels should still work, and devices nodes should be
-reliably created, but some rules and libudev will not work correctly because
-the old kernels do not provide the expected information or interfaces.
-
-udev 135
-========
-Bugfixes.
-
-Fix for a possible segfault while swapping network interface names in udev
-versions 131-134.
-
-udev 134
-========
-Bugfixes.
-
-The group "video" is part of the default rules now.
-
-udev 133
-========
-Bugfix for kernels using SYSFS_DEPRECATED* option and finding parent
-block devices in some cases. No common distro uses this option anymore,
-and we do not get enough testing for this and recent udev versions. If
-this option is not needed to run some old distro with a new kernel,
-it should be disabled in the kernel config.
-
-Bugfix for the $links substitution variable, which may crash if no links
-are created. This should not happen in usual setups because we always
-create /dev/{block,char}/ links.
-
-The strings of the parsed rules, which are kept in memory, no longer
-contain duplicate entries, or duplicate tails of strings. This, and the
-new rules parsing/matching code reduces the total in-memory size of
-a huge distro rule sets to 0.08 MB, compared to the 1.2MB of udev
-version 130.
-
-The export of DEVTYPE=disk/partition got removed from the default
-rules. This value is available from the kernel. The pnp shell script
-modprobe hack is removed from the default rules. ACPI devices have _proper_
-modalias support and take care of the same functionality.
-Installations which support old kernels, but install current default
-udev rules may want to add that to the compat rules file.
-
-Libvolume_id now always probes for all known filesystems, and does not
-stop at the first match. Some filesystems are marked as "exclusive probe",
-and if any other filesytem type matches at the same time, libvolume_id
-will, by default, not return any probing result. This is intended to prevent
-mis-detection with conflicting left-over signatures found from earlier
-file system formats. That way, we no longer depend on the probe-order
-in case of multiple competing signatures. In some setups the kernel allows
-to mount a volume with just the old filesystem signature still in place.
-This may damage the new filesystem and cause data-loss, just by mounting
-it. Because volume_id can not decide which one the correct signature is,
-the wrong signatures need to be removed manually from the volume, or the
-volume needs to be reformatted, to enable filesystem detection and possible
-auto-mounting.
-
-udev 132
-========
-Fix segfault if compiled without optimization and dbg() does not get
-compiled out and uses variables which are not available.
-
-udev 131
-========
-Bugfixes. (And maybe new bugs. :))
-
-The rule matching engine got converted from a rule list to a token
-array which reduced the in-memory rules representation of a full
-featured distros with thousends of udev rules from 1.2MB to 0.12 MB.
-Limits like 5 ENV and ATTR matches, and one single instance for most
-other keys per rule are gone.
-
-The NAME assignment is no longer special cased. If later rules assign
-a NAME value again, the former value will be overwritten. As usual
-for most other keys, the NAME value can be protected by doing a final
-assignment with NAME:="<value>".
-
-All udev code now uses libudev, which is also exported. The library
-is still under development, marked as experimental, and its interface
-may change as long as the DeviceKit integration is not finished.
-
-Many thanks to Alan Jenkins for his continuous help, and finding and
-optimizing some of the computing expensive parts.
-
-udev 130
-========
-Bugfixes.
-
-Kernel devices and device nodes are connected now by reverse indizes in
-/sys and /dev. A device number retrieved by a stat() or similar, the
-kernel device directory can be found by looking up:
- /sys/dev/{block,char}/<maj>:<min>
-and the device node of the same device by looking up:
- /dev/{block,char}/<maj>:<min>
-
-udev 129
-========
-Fix recently introduced bug, which caused a compilation without large
-file support, where vol_id does not recognize raid signatures at the end
-of a volume.
-
-Firewire disks now create both, by-id/scsi-* and by-id/ieee-* links.
-Seems some kernel versions prevent the creation of the ieee-* links,
-so people used the scsi-* link which disappeared now.
-
-More libudev work. Almost all udevadm functionality comes from libudev
-now.
-
-udevadm trigger has a new option --type, which allows to trigger events
-for "devices", for "subsystems", or "failed" devices. The old option
---retry-failed" still works, but is no longer mentioned in the man page.
-
-udev 128
-========
-Bugfixes.
-
-The udevadm info --device-id-of-file= output has changed to use
-the obvious format. Possible current users should use the --export
-option which is not affected.
-
-The old udev commands symlinks to udevadm are not installed, if
-these symlinks are used, a warning is printed.
-
-udev 127
-========
-Bugfixes.
-
-Optical drive's media is no longer probed for raid signatures,
-reading the end of the device causes some devices to malfunction.
-Also the offset of the last session found is used now to probe
-for the filesystem.
-
-The volume_id library got a major version number update to 1,
-some deprecated functions are removed.
-
-A shared library "libudev" gets installed now to provide access
-to udev device information. DeviceKit, the successor of HAL, will
-need this library to access the udev database and search sysfs for
-devices.
-The library is currently in an experimental state, also the API is
-expected to change, as long as the DeviceKit integration is not
-finished.
-
-udev 126
-========
-We use ./configure now. See INSTALL for details. Current
-options are:
- --prefix=
- "/usr" - prefix for man pages, include files
- --exec-prefix=
- "" - the root filesystem, prefix for libs and binaries
- --sysconfdir=
- "/etc"
- --with-libdir-name=
- "lib" - directory name for libraries, not a path name
- multilib 64bit systems may use "lib64" instead of "lib"
- --enable-debug
- compile-in verbose debug messages
- --disable-logging
- disable all logging and compile-out all log strings
- --with-selinux
- link against SELInux libraries, to set the expected context
- for created files
-
-In the default rules, the group "disk" gets permissions 0660 instead
-of 0640. One small step closer to unify distro rules. Some day, all
-distros hopefully end up with the same set of rules.
-
-No symlinks to udevadm are installed anymore, if they are still needed,
-they should be provided by the package.
-
-udev 125
-========
-Bugfixes.
-
-Default udev rules, which are not supposed to be edited by the user, should
-be placed in /lib/udev/rules.d/ now, to make it clear that they are private to
-the udev package and will be replaced with an update. Udev will pick up rule
-files from:
- /lib/udev/rules.d/ - default installed rules
- /etc/udev/rules.d/ - user rules + on-the-fly generated rules
- /dev/.udev/rules.d/ - temporary non-persistent rules created after bootup
-It does not matter in which directory a rule file lives, all files are sorted
-in lexical order.

-To help creating /dev/root, we have now:
- $ udevadm info --export --export-prefix="ROOT_" --device-id-of-file=/
- ROOT_MAJOR=8
- ROOT_MINOR=5
-In case the current --device-id-of-file is already used, please switch to
-the --export format version, it saves the output parsing and the old
-format will be changed to use ':' as a separator, like the format in the
-sysfs 'dev' file.

-Fix cdrom_id to properly recognize blank media.
-
-udev 123
-========
-Bugfixes.
-
-Tape drive id-data is queried from /dev/bsg/* instead of the tape
-nodes. This avoids rewinding tapes on open().
-
-udev 122
-========
-Bugfixes.
-
-The symlinks udevcontrol and udevtrigger are no longer installed by
-the Makefile.
-
-The scsi_id program does not depend on sysfs anymore. It can speak
-SGv4 now, so /dev/bsg/* device nodes can be used, to query SCSI device
-data, which should solve some old problems with tape devices, where
-we better do not open all tape device nodes to identify the device.
-
-udev 121
-========
-Many bugfixes.
-
-The cdrom_id program is replaced by an advanced version, which can
-detect most common device types, and also properties of the inserted
-media. This is part of moving some basic functionality from HAL into
-udev (and the kernel).
-
-udev 120
-========
-Bugfixes.
-
-The last WAIT_FOR_SYSFS rule is removed from the default rules.
-
-The symlinks to udevadm for the debugging tools: udevmonitor and
-udevtest are no longer created.
-
-The symlinks to the udevadm man page for the old tool names are
-no longer created.
-
-Abstract namespace sockets paths in RUN+="socket:@<path>" rules,
-should be prefixed with '@' to indicate that the path is not a
-real file.

-udev 119
-========
-Bugfixes.
-
-udev 118
-========
-Bugfixes.
-
-Udevstart is removed from the tree, it did not get installed for
-a long time now, and is long replaced by trigger and settle.
-
-udev 117
-========
-Bugfixes.
-
-All udev tools are merged into a single binary called udevadm.
-The old names of the tools are built-in commands in udevadm now.
-Symlinks to udevadm, with the names of the old tools, provide
-the same functionality as the standalone tools. There is also
-only a single udevadm.8 man page left for all tools.
-
-Tools like mkinitramfs should be checked, if they need to include
-udevadm in the list of files.
-
-udev 116
-========
-Bugfixes.
-
-udev 115
-========
-Bugfixes.
-
-The etc/udev/rules.d/ directory now contains a default set of basic
-udev rules. This initial version is the result of a rules file merge
-of Fedora and openSUSE. For these both distros only a few specific
-rules are left in their own file, named after the distro. Rules which
-are optionally installed, because they are only valid for a specific
-architecture, or rules for subsystems which are not always used are
-in etc/udev/packages/.
-
-udev 114
-========
-Bugfixes.
-
-Dynamic rules can be created in /dev/.udev/rules.d/ to trigger
-actions by dynamically created rules.
-
-SYMLINK=="<value>" matches agains the entries in the list of
-currently defined symlinks. The links are not created in the
-filesystem at that point in time, but the values can be matched.
