5 Udevstart is removed from the tree, it did not get installed for
6 a long time now, and is long replaced by trigger and settle.
12 All udev tools are merged into a single binary called udevadm.
13 The old names of the tools are built-in commands in udevadm now.
14 Symlinks to udevadm, with the names of the old tools, provide
15 the same functionality as the standalone tools. There is also
16 only a single udevadm.8 man page left for all tools.
18 Tools like mkinitramfs should be checked, if they need to include
19 udevadm in the list of files.
29 The etc/udev/rules.d/ directory now contains a default set of basic
30 udev rules. This initial version is the result of a rules file merge
31 of Fedora and openSUSE. For these both distros only a few specific
32 rules are left in their own file, named after the distro. Rules which
33 are optionally installed, because they are only valid for a specific
34 architecture, or rules for subsystems which are not always used are
35 in etc/udev/packages/.
41 Dynamic rules can be created in /dev/.udev/rules.d/ to trigger
42 actions by dynamically created rules.
44 SYMLINK=="<value>" matches agains the entries in the list of
45 currently defined symlinks. The links are not created in the
46 filesystem at that point in time, but the values can be matched.
48 RUN{ignore_error}+="<program>" will ignore any exit code from the
49 program and not record as a failed event.
55 Final merge of patches/features from the Ubuntu package.
61 Control characters in filesystem label strings are no longer silenty
62 removed, but hex-encoded, to be able to uniquely identify the device
63 by its symlink in /dev/disk/by-label/.
64 If libvolume_id is used by mount(8), LABEL= will work as expected,
65 if slashes or other characters are used in the label string.
67 To test the existence of a file, TEST=="<file>" and TEST!="<file>"
68 can be specified now. The TEST key accepts an optional mode mask
69 TEST{0100}=="<is executable file>".
71 Scsi_id now supports a mode without expecting scsi-specific sysfs
72 entries to allow the extraction of cciss-device persistent properties.
78 In the future, we may see uuid's which are just simple character
79 strings (see the DDF Raid Specification). For that reason vol_id now
80 exports ID_FS_UUID_SAFE, just like ID_FS_LABEL_SAFE. For things like
81 the creation of symlinks, the *_SAFE values ensure, that no control
82 or whitespace characters are used in the filename.
84 Possible users of libvolume_id, please use the volume_id_get_* functions.
85 The public struct will go away in a future release of the library.
91 Removal of useless extras/eventrecorder.sh.
101 The directory multiplexer for dev.d/ and hotplug.d are finally removed
102 from the udev package.
108 Symlinks can have priorities now, the priority is assigned to the device
109 and specified with OPTIONS="link_priority=100". Devices with higher
110 priorities overwrite the symlinks of devices with lower priorities.
111 If the device that currently owns the link, goes away, the symlink
112 will be removed, and recreated, pointing to the next device with the
113 highest actual priority. This should make /dev/disk/by-{label,uuid,id}
114 more reliable, if multiple devices contain the same metadata and overwrite
117 The dasd_id program is removed from the udev tree, and dasdinfo, with the
118 needed rules, are part of the s390-tools now.
120 Please add KERNEL=="[0-9]*:[0-9]*" to the scsi wait-for-sysfs rule,
121 we may get the scsi sysfs mess fixed some day, and this will only catch
122 the devices we are looking for.
124 USB serial numbers for storage devices have the target:lun now appended,
125 to make it possibble to distinguish broken multi-lun devices with all
126 the same SCSI identifiers.
128 Note: The extra "run_directory" which searches and executes stuff in
129 /etc/hotplug.d/ and /etc/dev.d/ is long deprecated, and will be removed
130 with the next release. Make sure, that you don't use it anymore, or
131 provides your own implementation of that inefficient stuff.
132 We are tired of reports about a "slow udev", because these directories
133 contain stuff, that runs with _every_ event, instead of using rules,
134 that run programs only for the matching events.
144 DRIVER== will match only for devices that actually have a real
145 driver. DRIVERS== must be used, if parent devices should be
146 included in the match.
148 Libvolume_id's "linux_raid" detection needed another fix.
156 Add additional check to volume_id detection of via_raid, cause
157 some company decided to put a matching pattern all over the empty
158 storage area of their music players.
162 Fix path_id for SAS devices.
166 The udev daemon can be started with --debug-trace now, which will
167 execute all events serialized to get a chance to catch a possible
168 action that crashes the box.
170 A warning is logged, if PHYSDEV* keys, the "device" link, or a parent
171 device attribute like $attr{../file} is used, only WAIT_FOR_SYSFS rules
172 are excluded from the warning. Referencing parent attributes directly
173 may break when something in the kernel driver model changes. Udev will
174 just find the attribute by walking up the parent chain.
176 Udevtrigger now sorts the list of devices depending on the device
177 dependency, so a "usb" device is triggered after the parent "pci"
182 Revert persistent-storage ata-serial '_' '-' replacement.
188 Udevtrigger can now filter the list of devices to be triggered. Matches
189 for subsystems or sysfs attributes can be specified.
191 The entries in /dev/.udev/queue and /dev/.udev/failed have changed to
192 zero-sized files to avoid pointing to /sys and confuse broken tools which
193 scan the /dev directory. To retry failed events, udevtrigger --retry-failed
196 The rules and scripts to create udev rules for persistent network
197 devices and optical drives are in the extras/rules_generator directory
198 now. If you use something similar, please consider replacing your own
199 version with this, to share the support effort. The rule_generator
200 installs its own rules into /etc/udev/rules.d.
202 The cdrom_id tool installs its own rule now in /etc/udev/rules.d, cause
203 the rule_generator depends on cdrom_id to be called in an earlier rule.
209 Renaming of some key names (the old names still work):
210 BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
211 (The behavior of the key DRIVER will change soon in one of the next
212 releases, to match only the event device, please switch to DRIVERS
213 instead. If DRIVER is used, it will behave like DRIVERS, but an error
215 With the new key names, we have a more consistent and simpler scheme.
216 We can match the properties of the event device only, with: KERNEL,
217 SUBSYSTEM, ATTR, DRIVER. Or include all the parent devices in the match,
218 with: KERNELS, SUBSYSTEMS, ATTRS, DRIVERS. ID, BUS, SYSFS, DRIVER are no
219 longer mentioned in the man page and should be switched in the rule
222 ATTR{file}="value" can be used now, to write to a sysfs file of the
223 event device. Instead of:
224 ..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
226 ..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
228 All the PHYSDEV* keys are deprecated and will be removed from a
230 PHYDEVPATH - is the path of a parent device and should not be
232 PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
233 matched with SUBSYSTEMS==
234 PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
235 Newer kernels will have DRIVER in the environment,
236 for older kernels udev puts in. Class device will
237 no longer carry this property of a parent and
238 DRIVERS== can be used to match such a parent value.
239 Note that ENV{DRIVER} is only available for a few bus devices, where
240 the driver is already bound at device event time. On coldplug, the
241 events for a lot devices are already bound to a driver, and they will have
242 that value set. But on hotplug, at the time the kernel creates the device,
243 it can't know what driver may claim the device after that, therefore
244 in most cases it will be empty.
246 Failed events should now be re-triggered with:
247 udevtrigger --retry-failed.
248 Please switch to this command, so we keep the details of the /dev/.udev/failed/
249 files private to the udev tools. We may need to switch the current symlink
250 target, cause some obviously broken tools try to scan all files in /dev
251 including /dev/.udev/, find the links to /sys and end up stat()'ing sysfs files
252 million times. This takes ages on slow boxes.
254 The udevinfo attribute walk (-a) now works with giving a device node
255 name (-n) instead of a devpath (-p). The query now always works, also when
256 no database file was created by udev.
258 The built-in /etc/passwd /etc/group parser is removed, we always depend on
259 getpwnam() and getgrnam() now. One of the next releases will depend on
260 fnmatch() and may use getopt_long().
264 Bugfixes and small improvements.
268 Fix path_id for recent kernels.
274 Added support for swapping network interface names, by temporarily
275 renaming the device and wait for the target name to become free.
279 The built-in MODALIAS key and substitution is removed.
283 The binary firmware helper is replaced by the usual simple
284 shell script. Udevsend is removed from the tree.
292 Some more keys require the correct use of '==' and '=' depending
293 on the kind of operation beeing an assignment or a match. Rules
294 with invalid operations are skipped and logged to syslog. Please
295 test with udevtest if the parsing of your rules throws errors and
296 fix possibly broken rules.
300 Provide "udevsettle" to wait for all current udev events to finish.
301 It also watches the current kernel netlink queue by comparing the
302 even sequence number to make sure that there are no current pending
303 events that have not already arrived in the daemon.
307 Fix rule to skip persistent rules for removable IDE devices, which
308 also skipped optical IDE drives.
310 All *_id program are installed in /lib/udev/ by default now.
312 No binary is stripped anymore as this should be done in the
313 packaging process and not at build time.
315 libvolume_id is provided as a shared library now and vol_id is
316 linked against it. Also one of the next HAL versions will require
317 this library, and the HAL build process will also require the
318 header file to be installed. The copy of the same code in HAL will
319 be removed to have only a single copy left on the system.
323 Add persistent links for SCSI tapes. The rules file is renamed
324 to 60-persistent-storage.rules.
326 Create persistent path for usb devices. Can be used for all sorts
327 of devices that can't be distinguished by other properties like
328 multiple identical keyboards and mice connected to the same box.
330 Provide "udevtrigger" program to request events on coldplug. The
331 shell script is much too slow with thousends of devices.
335 Fix persistent disk rules to exclude removable IDE drives.
337 Warn if %e, $modalias or MODALIAS is used.
341 Fix queue export, which wasn't correct for subsequent add/remove
342 events for the same device.
346 Fix cramfs detection on big endian.
348 Make WAIT_FOR_SYSFS usable in "normal" rules and silent if the whole
353 If BUS== and SYSFS{}== have been used in the same rule, the sysfs
354 attributes were only checked at the parent device that matched the
355 by BUS requested subsystem. Fix it to also look at the device we
356 received the event for.
358 Build variable CROSS has changed to CROSS_COMPILE to match the kernel
363 Fix a bug where NAME="" would prevent RUN from beeing executed.
365 RUN="/bin/program" does not longer automatically add the subsystem
366 as the first parameter. This is from the days of /sbin/hotplug
367 which is dead now and it's just confusing to need to add a space at
368 the end of the program name to prevent this.
369 If you use rules that need the subsystem as the first parameter,
370 like the old "udev_run_hotlugd" and "udev_run_devd", add the subsystem
371 to the key like RUN+="/bin/program $env{SUBSYSTEM}".
375 The udev man page has moved to udev(7) as it does not describe a command
376 anymore. The programs udev, udevstart and udevsend are no longer installed
377 by default and must be copied manually, if they should be installed or
378 included in a package.
380 Fix a bug where "ignore_device" could run earlier collected RUN keys before
381 the ignore rule was applied.
383 More preparation for future sysfs changes. usb_id and scsi_id no longer
384 depend on a magic order of devices in the /devices chain. Specific devices
385 should be requested by their subsytem.
387 This will always find the scsi parent device without depending on a specific
389 dev = sysfs_device_get(devpath);
390 dev_usb = sysfs_device_get_parent_with_subsystem(dev, "scsi");
392 The "device" link in the current sysfs layout will be automatically
393 _resolved_ as a parent and in the new sysfs layout it will just _be_ the
394 parent in the devpath. If a device is requested by it's symlink, like all
395 class devices in the new sysfs layout will look like, it gets automatically
396 resolved and substituted with the real devpath and not the symlink path.
399 A similar logic must be applied to _all_ sysfs users, including
400 scripts, that search along parent devices in sysfs. The explicit use of
401 the "device" link must be avoided. With the future sysfs layout all
402 DEVPATH's will start with /devices/ and have a "subsystem" symlink poiting
403 back to the "class" or the "bus". The layout of the parent devices in
404 /devices is not necessarily expected to be stable across kernel releases and
405 searching for parents by their subsystem should make sysfs users tolerant
406 for changed parent chains.
410 Prepare udev to work with the experimental kernel patch, that moves
411 /sys/class devices to /sys/devices and /sys/block to /sys/class/block.
413 Clarify BUS, ID, $id usage and fix $id behavior. This prepares for
414 moving the class devices to /sys/devices.
416 Thanks again to Marco for help finding a hopefully nice compromise
417 to make %b simpler and working again.
421 Complete removal of libsysfs, replaced by simple helper functions
422 which are much simpler and a bit faster. The udev daemon operatesentirely
423 on event parameters and does not use sysfs for simple rules anymore.
424 Please report any new bugs/problems, that may be caused by this big
425 change. They will be fixed immediately.
427 The enumeration format character '%e' is deprecated and will be
428 removed sometimes from a future udev version. It never worked correctly
429 outside of udevstart, so we can't use it with the new parallel
430 coldplug. A simple enumeration is as useless as the devfs naming
431 scheme, just get rid of both if you still use it.
433 MODALIAS and $modalias is not needed and will be removed from one of
434 the next udev versions, replace it in all rules with ENV{MODALIAS} or
435 the sysfs "modalias" value.
437 Thanks a lot to Marco for all his help on finding and fixing bugs.
441 Let scsi_id request libata drive serial numbers from page 0x80.
443 Renamed etc/udev/persistent.rules to persistent-disk.rules and
444 added /dev/disk/by-name/* for device mapper device names.
446 Removed %e from the man page. It never worked reliably outside
447 of udevstart and udevstart is no longer recommended to use.
451 Symlinks are now exported to the event environment. Hopefully it's no
452 longer needed to run udevinfo from an event process, like it was
453 mentioned on the hotplug list:
454 UDEV [1134776873.702967] add@/block/sdb
457 DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0
461 Fix a problem if udevsend is used as the hotplug handler and tries to use
462 syslog, which causes a "vc" event loop. 2.6.15 will make udevsend obsolete
463 and this kind of problems will hopefully go away soon.
467 All built-in logic to work around bad sysfs timing is removed with this
468 version. The need to wait for sysfs files is almost fixed with a kernel
469 version that doesn't work with this udev version anyway. Until we fix
470 the timing of the "bus" link creation, the former integrated logic should
471 be emulated by a rule placed before all other rules:
472 ACTION=="add", DEVPATH=="/devices/*", ENV{PHYSDEVBUS}=="?*", WAIT_FOR_SYSFS="bus"
474 The option "udev_db" does no longer exist. All udev state will be in
475 /$udev_root/.udev/ now, there is no longer an option to set this
477 If the init script or something else used this value, just depend on
478 this hardcoded path. But remember _all_content_ of this directory is
479 still private to udev and can change at any time.
481 Default location for rule sripts and helper programs is now: /lib/udev/.
482 Everything that is not useful on the commandline should go into this
483 directory. Some of the helpers in the extras folder are installed there
484 now. The rules need to be changed, to find the helpers there.
486 Also /lib/udev/devices is recommended as a directory where packages or
487 the user can place real device nodes, which get copied over to /dev at
488 every boot. This should replace the various solutions with custom config
491 Udevsend does no longer start the udev daemon. This must be done with
492 the init script that prepares /dev on tmpfs and creates the initial nodes,
493 before starting the daemon.
497 Silent a too verbose error logging for the old hotplug.d/ dev.d/
500 The copy of klibc is removed. A systemwide installed version of klibc
501 should be used to build a klibc udev now.
505 NAME="" will not create any nodes, but execute RUN keys. To completely
506 ignore an event the OPTION "ignore_device" should be used.
508 After removal of the reorder queue, events with a TIMEOUT can be executed
509 without any queuing now.
513 Fixed bug in udevd, if inotify is not available. We depend on netlink
514 uevents now, kernels without that event source will not work with that
515 version of udev anymore.
519 The rule parsing happens now in the daemon once at startup, all udev
520 event processes inherit the already parsed rules from the daemon.
521 It is shipped with SUSE10.0 and reduces heavily the system load at
522 startup. The option to save precompiled rules and let the udev process
523 pick the them up is removed, as it's no longer needed.
525 Kernel 2.6.15 will have symlinks at /class/input pointing to the real
526 device. Libsysfs is changed to "translate" the requested link into the
527 real device path, as it would happen with the hotplug event. Otherwise
528 device removal and the udev database will not work.
530 Using 'make STRIPCMD=' will leave the binaries unstripped for debugging
533 A few improvements for vol_id, the filesytem probing code.
537 Fix a stupid typo in extras/run_directory for "make install".
539 scsi_id creates the temporary devnode now in /dev for usage with a
540 non-writable /tmp directory.
542 The uevent kernel socket buffer can carry app. 50.000 events now,
543 let's see who can break this again. :)
545 The upcoming kernel will have a new input driver core integration.
546 Some class devices are now symlinks to the real device. libsysfs
547 needs a fix for this to work correctly. Udevstart of older udev
548 versions will _not_ create these devices!
552 Fix a 'install' target in the Makefile, that prevents EXTRAS from
557 A bunch of mostly trivial bugfixes. From now on no node name or
558 symlink name can contain any character than plain whitelisted ascii
559 characters or validated utf8 byte-streams. This is needed for the
560 /dev/disk/by-label/* links, because we import untrusted data and
561 export it to the filesystem.
565 More bugfixes. If udevd was started from the kernel, we don't
566 have stdin/stdout/stderr, which broke the forked tools in some
571 Bugfix. udevstart event ordering was broken for a long time.
572 The new run_program() uncovered it, because /dev/null was not
573 available while we try to run external programs.
574 Now udevstart should create it before we run anything.
578 Minor bugfixes and some distro rules updates. If you don't have the
579 persistent disk rules in /dev/disk/by-*/* on your distro, just
580 grab it from here. :)
584 We can use socket communication now to pass events from udev to
586 RUN+="socket:/org/freedesktop/hal/udev_event"
587 will pass the whole udev event to the HAL daemon without the need
588 for a forked helper. (See ChangeLog for udevmonitor, as an example)
592 Mostly bugfixes and see ChangeLog.
594 The test for the existence of an environment value should be
596 ENV{KEY}=="*" to ENV{KEY}=="?*"
597 because "*" will not fail anymore, if the key does not exist or
602 Bugfixes and a few tweaks described in the ChangeLog.
606 Mostly a Bugfix release.
608 Added WAIT_FOR_SYSFS="<attribute>" to be able to fight against the sysfs
609 timing with custom rules.
613 We changed the internal rule storage format. Our large rule files took
614 2 MB of RAM, with the change we are down to 99kB.
616 If the device-node has been created with default name and no symlink or
617 options are to remenber, it is not longer stored in the udevdb. HAL will
618 need to be updated to work correctly with that change.
620 To overrride optimization flags, OPTFLAGS may be used now.
628 Major changes happened with this release. The goal is to take over the
629 complete kernel-event handling and provide a more efficient way to dispatch
630 kernel events. Replacing most of the current shell script logic and the
631 kernel forked helper with a netlink-daemon and a rule-based event handling.
633 o udevd listens to netlink events now. The first valid netlink event
634 will make udevd ignore any message from udevsend that contains a
635 SEQNUM, to avoid duplicate events. The forked events can be disabled
637 echo "" > /proc/sys/kernel/hotplug
638 For full support, the broken input-subsytem needs to be fixed, not to
639 bypass the driver core.
641 o /etc/dev.d/ + /etc/hotplug.d/ directory multiplexing is completely
642 removed from udev itself and must be emulated by calling small
643 helper binaries provided in the extras folder:
644 make EXTRAS=extras/run_directory/
645 will build udev_run_devd and udev_run_hotplugd, which can be called
646 from a rule if needed:
647 RUN+="/sbin/udev_run_hotplugd"
648 The recommended way to handle this is to convert all the calls from
649 the directories to explicit udev rules and get completely rid of the
650 multiplexing. (To catch a ttyUSB event, you now no longer need to
651 fork and exit 300 tty script instances you are not interested in, it
652 is just one rule that matches exactly the device.)
654 o udev handles now _all_ events not just events for class and block
655 devices, this way it is possible to control the complete event
656 behavior with udev rules. Especially useful for rules like:
657 ACTION="add", DEVPATH="/devices/*", MODALIAS=="?*", RUN+="/sbin/modprobe $modalias"
659 o As used in the modalias rule, udev supports now textual
660 substitution placeholder along with the usual format chars. This
661 needs to be documented, for now it's only visible in udev_rules_parse.c.
663 o The rule keys support now more operations. This is documented in the
664 man page. It is possible to add values to list-keys like the SYMLINK
665 and RUN list with KEY+="value" and to clear the list by assigning KEY="".
666 Also "final"-assignments are supported by using KEY:="value", which will
667 prevent changing the key by any later rule.
669 o kernel 2.6.12 has the "detached_state" attribute removed from
670 sysfs, which was used to recognize sysfs population. We switched that
671 to wait for the "bus" link, which is only available in kernels after 2.6.11.
672 Running this udev version on older kernels may cause a short delay for
675 o To provide infrastructure for persistent device naming, the id programs:
676 scsi_id, vol_id (former udev_volume_id), and ata_id (new) are able now
677 to export the probed data in environment key format:
678 pim:~ # /sbin/ata_id --export /dev/hda
679 ID_MODEL=HTS726060M9AT00
680 ID_SERIAL=MRH401M4G6UM9B
684 KERNEL="hd*[!0-9]", IMPORT="/sbin/ata_id --export $tempnode"
685 KERNEL="hd*[!0-9]", ENV{ID_SERIAL}=="?*", SYMLINK+="disk/by-id/$env{ID_MODEL}_$env{ID_SERIAL}"
688 kay@pim:~> tree /dev/disk

703 The IMPORT= operation will import these keys in the environment and make
704 it available for later PROGRAM= and RUN= executed programs. The keys are
705 also stored in the udevdb and can be queried from there with one of the
708 o A few binaries are silently added to the repository, which can be used
709 to replay kernel events from initramfs instead of using coldplug. udevd
710 can be instructed now to queue-up events while the stored events from
711 initramfs are filled into the udevd-queue. This code is still under
712 development and there is no documentation now besides the code itself.
713 The additional binaries get compiled, but are not installed by default.
715 o There is also a temporary fix for a performance problem where too many
716 events happen in parallel and every event needs to parse the rules.
717 udev can now read precompiled rules stored on disk. This is likely to be
718 replaced by a more elegant solution in a future udev version.
722 With kernel version 2.6.12, the sysfs file "detached_state" was removed.
723 Fix for libsysfs not to expect this file was added.
727 All rules are applied now, but only the first matching rule with a NAME-key
728 will be applied. All later rules with NAME-key are completely ignored. This
729 way system supplied symlinks or permissions gets applied to user-defined
733 Please check your rules setup, if you may need to add OPTIONS="last_rule"
734 to some rules, to keep the old behavior.
736 The rules are read on "remove"-events too. That makes is possible to match
737 with keys that are available on remove (KERNEL, SUBSYSTEM, ID, ENV, ...) to
738 instruct udev to ignore an event (OPTIONS="ignore_device").
739 The new ACTION-key may be used to let a rule act only at a "remove"-event.
741 The new RUN-key supports rule-based execution of programs after device-node
742 handling. This is meant as a general replacement for the dev.d/-directories
743 to give fine grained control over the execution of programs.
745 The %s{}-sysfs format char replacement values are searched at any of the
746 devices in the device chain now, not only at the class-device.
748 We support log priority levels now. The value udev_log in udev.conf is used
749 to determine what is printed to syslog. This makes it possible to
750 run a version with compiled-in debug messages in a production environment
751 which is sometimes needed to find a bug.
752 It is still possible to supress the inclusion of _any_ syslog usage with
753 USE_LOG=false to create the smallest possible binaries if needed.
754 The configured udev_log value can be overridden with the environment variable
759 Possible use of a system-wide klibc:
760 make USE_KLIBC=true KLCC=/usr/bin/klcc all
761 will link against an external klibc and our own version will be ignored.
765 We support an unlimited count of symlinks now.
767 If USE_STATIC=true is passed to a glibc build, we link statically and use
768 a built-in userdb parser to resolve user and group names.
770 The PLACE= key is gone. It can be replaced by an ID= for a long time, because
771 we walk up the chain of physical devices to find a match.
773 The KEY="<value>" format supports '=', '==', '!=,' , '+=' now. This makes it
774 easy to skip certain attribute matches without composing rules with weird
775 character class negations like:
776 KERNEL="[!s][!c][!d]*"
777 this can now be replaced with:
779 The current simple '=' is still supported, and should work as it does today,
780 but existing rules should be converted if possible, to be better readable.
782 We have new ENV{}== key now, to match against a maximum of 5 environment
785 udevstart is its own binary again, because we don't need co carry this araound
786 with every forked event.
