9 The etc/udev/rules.d/ directory now contains a default set of basic
10 udev rules. This initial version is the result of a rules file merge
11 of Fedora and openSUSE. For these both distros only a few specific
12 rules are left in their own file, named after the distro. Rules which
13 are optionally installed, because they are only valid for a specific
14 architecture, or rules for subsystems which are not always used are
15 in etc/udev/packages/.
21 Dynamic rules can be created in /dev/.udev/rules.d/ to trigger
22 actions by dynamically created rules.
24 SYMLINK=="<value>" matches agains the entries in the list of
25 currently defined symlinks. The links are not created in the
26 filesystem at that point in time, but the values can be matched.
28 RUN{ignore_error}+="<program>" will ignore any exit code from the
29 program and not record as a failed event.
35 Final merge of patches/features from the Ubuntu package.
41 Control characters in filesystem label strings are no longer silenty
42 removed, but hex-encoded, to be able to uniquely identify the device
43 by its symlink in /dev/disk/by-label/.
44 If libvolume_id is used by mount(8), LABEL= will work as expected,
45 if slashes or other characters are used in the label string.
47 To test the existence of a file, TEST=="<file>" and TEST!="<file>"
48 can be specified now. The TEST key accepts an optional mode mask
49 TEST{0100}=="<is executable file>".
51 Scsi_id now supports a mode without expecting scsi-specific sysfs
52 entries to allow the extraction of cciss-device persistent properties.
58 In the future, we may see uuid's which are just simple character
59 strings (see the DDF Raid Specification). For that reason vol_id now
60 exports ID_FS_UUID_SAFE, just like ID_FS_LABEL_SAFE. For things like
61 the creation of symlinks, the *_SAFE values ensure, that no control
62 or whitespace characters are used in the filename.
64 Possible users of libvolume_id, please use the volume_id_get_* functions.
65 The public struct will go away in a future release of the library.
71 Removal of useless extras/eventrecorder.sh.
81 The directory multiplexer for dev.d/ and hotplug.d are finally removed
82 from the udev package.
88 Symlinks can have priorities now, the priority is assigned to the device
89 and specified with OPTIONS="link_priority=100". Devices with higher
90 priorities overwrite the symlinks of devices with lower priorities.
91 If the device that currently owns the link, goes away, the symlink
92 will be removed, and recreated, pointing to the next device with the
93 highest actual priority. This should make /dev/disk/by-{label,uuid,id}
94 more reliable, if multiple devices contain the same metadata and overwrite
97 The dasd_id program is removed from the udev tree, and dasdinfo, with the
98 needed rules, are part of the s390-tools now.
100 Please add KERNEL=="[0-9]*:[0-9]*" to the scsi wait-for-sysfs rule,
101 we may get the scsi sysfs mess fixed some day, and this will only catch
102 the devices we are looking for.
104 USB serial numbers for storage devices have the target:lun now appended,
105 to make it possibble to distinguish broken multi-lun devices with all
106 the same SCSI identifiers.
108 Note: The extra "run_directory" which searches and executes stuff in
109 /etc/hotplug.d/ and /etc/dev.d/ is long deprecated, and will be removed
110 with the next release. Make sure, that you don't use it anymore, or
111 provides your own implementation of that inefficient stuff.
112 We are tired of reports about a "slow udev", because these directories
113 contain stuff, that runs with _every_ event, instead of using rules,
114 that run programs only for the matching events.
124 DRIVER== will match only for devices that actually have a real
125 driver. DRIVERS== must be used, if parent devices should be
126 included in the match.
128 Libvolume_id's "linux_raid" detection needed another fix.
136 Add additional check to volume_id detection of via_raid, cause
137 some company decided to put a matching pattern all over the empty
138 storage area of their music players.
142 Fix path_id for SAS devices.
146 The udev daemon can be started with --debug-trace now, which will
147 execute all events serialized to get a chance to catch a possible
148 action that crashes the box.
150 A warning is logged, if PHYSDEV* keys, the "device" link, or a parent
151 device attribute like $attr{../file} is used, only WAIT_FOR_SYSFS rules
152 are excluded from the warning. Referencing parent attributes directly
153 may break when something in the kernel driver model changes. Udev will
154 just find the attribute by walking up the parent chain.
156 Udevtrigger now sorts the list of devices depending on the device
157 dependency, so a "usb" device is triggered after the parent "pci"
162 Revert persistent-storage ata-serial '_' '-' replacement.
168 Udevtrigger can now filter the list of devices to be triggered. Matches
169 for subsystems or sysfs attributes can be specified.
171 The entries in /dev/.udev/queue and /dev/.udev/failed have changed to
172 zero-sized files to avoid pointing to /sys and confuse broken tools which
173 scan the /dev directory. To retry failed events, udevtrigger --retry-failed
176 The rules and scripts to create udev rules for persistent network
177 devices and optical drives are in the extras/rules_generator directory
178 now. If you use something similar, please consider replacing your own
179 version with this, to share the support effort. The rule_generator
180 installs its own rules into /etc/udev/rules.d.
182 The cdrom_id tool installs its own rule now in /etc/udev/rules.d, cause
183 the rule_generator depends on cdrom_id to be called in an earlier rule.
189 Renaming of some key names (the old names still work):
190 BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
191 (The behavior of the key DRIVER will change soon in one of the next
192 releases, to match only the event device, please switch to DRIVERS
193 instead. If DRIVER is used, it will behave like DRIVERS, but an error
195 With the new key names, we have a more consistent and simpler scheme.
196 We can match the properties of the event device only, with: KERNEL,
197 SUBSYSTEM, ATTR, DRIVER. Or include all the parent devices in the match,
198 with: KERNELS, SUBSYSTEMS, ATTRS, DRIVERS. ID, BUS, SYSFS, DRIVER are no
199 longer mentioned in the man page and should be switched in the rule
202 ATTR{file}="value" can be used now, to write to a sysfs file of the
203 event device. Instead of:
204 ..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
206 ..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
208 All the PHYSDEV* keys are deprecated and will be removed from a
210 PHYDEVPATH - is the path of a parent device and should not be
212 PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
213 matched with SUBSYSTEMS==
214 PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
215 Newer kernels will have DRIVER in the environment,
216 for older kernels udev puts in. Class device will
217 no longer carry this property of a parent and
218 DRIVERS== can be used to match such a parent value.
219 Note that ENV{DRIVER} is only available for a few bus devices, where
220 the driver is already bound at device event time. On coldplug, the
221 events for a lot devices are already bound to a driver, and they will have
222 that value set. But on hotplug, at the time the kernel creates the device,
223 it can't know what driver may claim the device after that, therefore
224 in most cases it will be empty.
226 Failed events should now be re-triggered with:
227 udevtrigger --retry-failed.
228 Please switch to this command, so we keep the details of the /dev/.udev/failed/
229 files private to the udev tools. We may need to switch the current symlink
230 target, cause some obviously broken tools try to scan all files in /dev
231 including /dev/.udev/, find the links to /sys and end up stat()'ing sysfs files
232 million times. This takes ages on slow boxes.
234 The udevinfo attribute walk (-a) now works with giving a device node
235 name (-n) instead of a devpath (-p). The query now always works, also when
236 no database file was created by udev.
238 The built-in /etc/passwd /etc/group parser is removed, we always depend on
239 getpwnam() and getgrnam() now. One of the next releases will depend on
240 fnmatch() and may use getopt_long().
244 Bugfixes and small improvements.
248 Fix path_id for recent kernels.
254 Added support for swapping network interface names, by temporarily
255 renaming the device and wait for the target name to become free.
259 The built-in MODALIAS key and substitution is removed.
263 The binary firmware helper is replaced by the usual simple
264 shell script. Udevsend is removed from the tree.
272 Some more keys require the correct use of '==' and '=' depending
273 on the kind of operation beeing an assignment or a match. Rules
274 with invalid operations are skipped and logged to syslog. Please
275 test with udevtest if the parsing of your rules throws errors and
276 fix possibly broken rules.
280 Provide "udevsettle" to wait for all current udev events to finish.
281 It also watches the current kernel netlink queue by comparing the
282 even sequence number to make sure that there are no current pending
283 events that have not already arrived in the daemon.
287 Fix rule to skip persistent rules for removable IDE devices, which
288 also skipped optical IDE drives.
290 All *_id program are installed in /lib/udev/ by default now.
292 No binary is stripped anymore as this should be done in the
293 packaging process and not at build time.
295 libvolume_id is provided as a shared library now and vol_id is
296 linked against it. Also one of the next HAL versions will require
297 this library, and the HAL build process will also require the
298 header file to be installed. The copy of the same code in HAL will
299 be removed to have only a single copy left on the system.
303 Add persistent links for SCSI tapes. The rules file is renamed
304 to 60-persistent-storage.rules.
306 Create persistent path for usb devices. Can be used for all sorts
307 of devices that can't be distinguished by other properties like
308 multiple identical keyboards and mice connected to the same box.
310 Provide "udevtrigger" program to request events on coldplug. The
311 shell script is much too slow with thousends of devices.
315 Fix persistent disk rules to exclude removable IDE drives.
317 Warn if %e, $modalias or MODALIAS is used.
321 Fix queue export, which wasn't correct for subsequent add/remove
322 events for the same device.
326 Fix cramfs detection on big endian.
328 Make WAIT_FOR_SYSFS usable in "normal" rules and silent if the whole
333 If BUS== and SYSFS{}== have been used in the same rule, the sysfs
334 attributes were only checked at the parent device that matched the
335 by BUS requested subsystem. Fix it to also look at the device we
336 received the event for.
338 Build variable CROSS has changed to CROSS_COMPILE to match the kernel
343 Fix a bug where NAME="" would prevent RUN from beeing executed.
345 RUN="/bin/program" does not longer automatically add the subsystem
346 as the first parameter. This is from the days of /sbin/hotplug
347 which is dead now and it's just confusing to need to add a space at
348 the end of the program name to prevent this.
349 If you use rules that need the subsystem as the first parameter,
350 like the old "udev_run_hotlugd" and "udev_run_devd", add the subsystem
351 to the key like RUN+="/bin/program $env{SUBSYSTEM}".
355 The udev man page has moved to udev(7) as it does not describe a command
356 anymore. The programs udev, udevstart and udevsend are no longer installed
357 by default and must be copied manually, if they should be installed or
358 included in a package.
360 Fix a bug where "ignore_device" could run earlier collected RUN keys before
361 the ignore rule was applied.
363 More preparation for future sysfs changes. usb_id and scsi_id no longer
364 depend on a magic order of devices in the /devices chain. Specific devices
365 should be requested by their subsytem.
367 This will always find the scsi parent device without depending on a specific
369 dev = sysfs_device_get(devpath);
370 dev_usb = sysfs_device_get_parent_with_subsystem(dev, "scsi");
372 The "device" link in the current sysfs layout will be automatically
373 _resolved_ as a parent and in the new sysfs layout it will just _be_ the
374 parent in the devpath. If a device is requested by it's symlink, like all
375 class devices in the new sysfs layout will look like, it gets automatically
376 resolved and substituted with the real devpath and not the symlink path.
379 A similar logic must be applied to _all_ sysfs users, including
380 scripts, that search along parent devices in sysfs. The explicit use of
381 the "device" link must be avoided. With the future sysfs layout all
382 DEVPATH's will start with /devices/ and have a "subsystem" symlink poiting
383 back to the "class" or the "bus". The layout of the parent devices in
384 /devices is not necessarily expected to be stable across kernel releases and
385 searching for parents by their subsystem should make sysfs users tolerant
386 for changed parent chains.
390 Prepare udev to work with the experimental kernel patch, that moves
391 /sys/class devices to /sys/devices and /sys/block to /sys/class/block.
393 Clarify BUS, ID, $id usage and fix $id behavior. This prepares for
394 moving the class devices to /sys/devices.
396 Thanks again to Marco for help finding a hopefully nice compromise
397 to make %b simpler and working again.
401 Complete removal of libsysfs, replaced by simple helper functions
402 which are much simpler and a bit faster. The udev daemon operatesentirely
403 on event parameters and does not use sysfs for simple rules anymore.
404 Please report any new bugs/problems, that may be caused by this big
405 change. They will be fixed immediately.
407 The enumeration format character '%e' is deprecated and will be
408 removed sometimes from a future udev version. It never worked correctly
409 outside of udevstart, so we can't use it with the new parallel
410 coldplug. A simple enumeration is as useless as the devfs naming
411 scheme, just get rid of both if you still use it.
413 MODALIAS and $modalias is not needed and will be removed from one of
414 the next udev versions, replace it in all rules with ENV{MODALIAS} or
415 the sysfs "modalias" value.
417 Thanks a lot to Marco for all his help on finding and fixing bugs.
421 Let scsi_id request libata drive serial numbers from page 0x80.
423 Renamed etc/udev/persistent.rules to persistent-disk.rules and
424 added /dev/disk/by-name/* for device mapper device names.
426 Removed %e from the man page. It never worked reliably outside
427 of udevstart and udevstart is no longer recommended to use.
431 Symlinks are now exported to the event environment. Hopefully it's no
432 longer needed to run udevinfo from an event process, like it was
433 mentioned on the hotplug list:
434 UDEV [1134776873.702967] add@/block/sdb
437 DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0
441 Fix a problem if udevsend is used as the hotplug handler and tries to use
442 syslog, which causes a "vc" event loop. 2.6.15 will make udevsend obsolete
443 and this kind of problems will hopefully go away soon.
447 All built-in logic to work around bad sysfs timing is removed with this
448 version. The need to wait for sysfs files is almost fixed with a kernel
449 version that doesn't work with this udev version anyway. Until we fix
450 the timing of the "bus" link creation, the former integrated logic should
451 be emulated by a rule placed before all other rules:
452 ACTION=="add", DEVPATH=="/devices/*", ENV{PHYSDEVBUS}=="?*", WAIT_FOR_SYSFS="bus"
454 The option "udev_db" does no longer exist. All udev state will be in
455 /$udev_root/.udev/ now, there is no longer an option to set this
457 If the init script or something else used this value, just depend on
458 this hardcoded path. But remember _all_content_ of this directory is
459 still private to udev and can change at any time.
461 Default location for rule sripts and helper programs is now: /lib/udev/.
462 Everything that is not useful on the commandline should go into this
463 directory. Some of the helpers in the extras folder are installed there
464 now. The rules need to be changed, to find the helpers there.
466 Also /lib/udev/devices is recommended as a directory where packages or
467 the user can place real device nodes, which get copied over to /dev at
468 every boot. This should replace the various solutions with custom config
471 Udevsend does no longer start the udev daemon. This must be done with
472 the init script that prepares /dev on tmpfs and creates the initial nodes,
473 before starting the daemon.
477 Silent a too verbose error logging for the old hotplug.d/ dev.d/
480 The copy of klibc is removed. A systemwide installed version of klibc
481 should be used to build a klibc udev now.
485 NAME="" will not create any nodes, but execute RUN keys. To completely
486 ignore an event the OPTION "ignore_device" should be used.
488 After removal of the reorder queue, events with a TIMEOUT can be executed
489 without any queuing now.
493 Fixed bug in udevd, if inotify is not available. We depend on netlink
494 uevents now, kernels without that event source will not work with that
495 version of udev anymore.
499 The rule parsing happens now in the daemon once at startup, all udev
500 event processes inherit the already parsed rules from the daemon.
501 It is shipped with SUSE10.0 and reduces heavily the system load at
502 startup. The option to save precompiled rules and let the udev process
503 pick the them up is removed, as it's no longer needed.
505 Kernel 2.6.15 will have symlinks at /class/input pointing to the real
506 device. Libsysfs is changed to "translate" the requested link into the
507 real device path, as it would happen with the hotplug event. Otherwise
508 device removal and the udev database will not work.
510 Using 'make STRIPCMD=' will leave the binaries unstripped for debugging
513 A few improvements for vol_id, the filesytem probing code.
517 Fix a stupid typo in extras/run_directory for "make install".
519 scsi_id creates the temporary devnode now in /dev for usage with a
520 non-writable /tmp directory.
522 The uevent kernel socket buffer can carry app. 50.000 events now,
523 let's see who can break this again. :)
525 The upcoming kernel will have a new input driver core integration.
526 Some class devices are now symlinks to the real device. libsysfs
527 needs a fix for this to work correctly. Udevstart of older udev
528 versions will _not_ create these devices!
532 Fix a 'install' target in the Makefile, that prevents EXTRAS from
537 A bunch of mostly trivial bugfixes. From now on no node name or
538 symlink name can contain any character than plain whitelisted ascii
539 characters or validated utf8 byte-streams. This is needed for the
540 /dev/disk/by-label/* links, because we import untrusted data and
541 export it to the filesystem.
545 More bugfixes. If udevd was started from the kernel, we don't
546 have stdin/stdout/stderr, which broke the forked tools in some
551 Bugfix. udevstart event ordering was broken for a long time.
552 The new run_program() uncovered it, because /dev/null was not
553 available while we try to run external programs.
554 Now udevstart should create it before we run anything.
558 Minor bugfixes and some distro rules updates. If you don't have the
559 persistent disk rules in /dev/disk/by-*/* on your distro, just
560 grab it from here. :)
564 We can use socket communication now to pass events from udev to
566 RUN+="socket:/org/freedesktop/hal/udev_event"
567 will pass the whole udev event to the HAL daemon without the need
568 for a forked helper. (See ChangeLog for udevmonitor, as an example)
572 Mostly bugfixes and see ChangeLog.
574 The test for the existence of an environment value should be
576 ENV{KEY}=="*" to ENV{KEY}=="?*"
577 because "*" will not fail anymore, if the key does not exist or
582 Bugfixes and a few tweaks described in the ChangeLog.
586 Mostly a Bugfix release.
588 Added WAIT_FOR_SYSFS="<attribute>" to be able to fight against the sysfs
589 timing with custom rules.
593 We changed the internal rule storage format. Our large rule files took
594 2 MB of RAM, with the change we are down to 99kB.
596 If the device-node has been created with default name and no symlink or
597 options are to remenber, it is not longer stored in the udevdb. HAL will
598 need to be updated to work correctly with that change.
600 To overrride optimization flags, OPTFLAGS may be used now.
608 Major changes happened with this release. The goal is to take over the
609 complete kernel-event handling and provide a more efficient way to dispatch
610 kernel events. Replacing most of the current shell script logic and the
611 kernel forked helper with a netlink-daemon and a rule-based event handling.
613 o udevd listens to netlink events now. The first valid netlink event
614 will make udevd ignore any message from udevsend that contains a
615 SEQNUM, to avoid duplicate events. The forked events can be disabled
617 echo "" > /proc/sys/kernel/hotplug
618 For full support, the broken input-subsytem needs to be fixed, not to
619 bypass the driver core.
621 o /etc/dev.d/ + /etc/hotplug.d/ directory multiplexing is completely
622 removed from udev itself and must be emulated by calling small
623 helper binaries provided in the extras folder:
624 make EXTRAS=extras/run_directory/
625 will build udev_run_devd and udev_run_hotplugd, which can be called
626 from a rule if needed:
627 RUN+="/sbin/udev_run_hotplugd"
628 The recommended way to handle this is to convert all the calls from
629 the directories to explicit udev rules and get completely rid of the
630 multiplexing. (To catch a ttyUSB event, you now no longer need to
631 fork and exit 300 tty script instances you are not interested in, it
632 is just one rule that matches exactly the device.)
634 o udev handles now _all_ events not just events for class and block
635 devices, this way it is possible to control the complete event
636 behavior with udev rules. Especially useful for rules like:
637 ACTION="add", DEVPATH="/devices/*", MODALIAS=="?*", RUN+="/sbin/modprobe $modalias"
639 o As used in the modalias rule, udev supports now textual
640 substitution placeholder along with the usual format chars. This
641 needs to be documented, for now it's only visible in udev_rules_parse.c.
643 o The rule keys support now more operations. This is documented in the
644 man page. It is possible to add values to list-keys like the SYMLINK
645 and RUN list with KEY+="value" and to clear the list by assigning KEY="".
646 Also "final"-assignments are supported by using KEY:="value", which will
647 prevent changing the key by any later rule.
649 o kernel 2.6.12 has the "detached_state" attribute removed from
650 sysfs, which was used to recognize sysfs population. We switched that
651 to wait for the "bus" link, which is only available in kernels after 2.6.11.
652 Running this udev version on older kernels may cause a short delay for
655 o To provide infrastructure for persistent device naming, the id programs:
656 scsi_id, vol_id (former udev_volume_id), and ata_id (new) are able now
657 to export the probed data in environment key format:
658 pim:~ # /sbin/ata_id --export /dev/hda
659 ID_MODEL=HTS726060M9AT00
660 ID_SERIAL=MRH401M4G6UM9B
664 KERNEL="hd*[!0-9]", IMPORT="/sbin/ata_id --export $tempnode"
665 KERNEL="hd*[!0-9]", ENV{ID_SERIAL}=="?*", SYMLINK+="disk/by-id/$env{ID_MODEL}_$env{ID_SERIAL}"
668 kay@pim:~> tree /dev/disk
671 | |-- HTS726060M9AT00_MRH401M4G6UM9B -> ../../hda
672 | `-- IBM-Memory_Key -> ../../sda
674 | |-- swap -> ../../hda1
675 | |-- date -> ../../sda1

678 |-- 2E08712B0870F2E7 -> ../../hda3

681 `-- b2a61681-3812-4f13-a4ff-920d70604299 -> ../../hda2
683 The IMPORT= operation will import these keys in the environment and make
684 it available for later PROGRAM= and RUN= executed programs. The keys are
685 also stored in the udevdb and can be queried from there with one of the
688 o A few binaries are silently added to the repository, which can be used
689 to replay kernel events from initramfs instead of using coldplug. udevd
690 can be instructed now to queue-up events while the stored events from
691 initramfs are filled into the udevd-queue. This code is still under
692 development and there is no documentation now besides the code itself.
693 The additional binaries get compiled, but are not installed by default.
695 o There is also a temporary fix for a performance problem where too many
696 events happen in parallel and every event needs to parse the rules.
697 udev can now read precompiled rules stored on disk. This is likely to be
698 replaced by a more elegant solution in a future udev version.
702 With kernel version 2.6.12, the sysfs file "detached_state" was removed.
703 Fix for libsysfs not to expect this file was added.
707 All rules are applied now, but only the first matching rule with a NAME-key
708 will be applied. All later rules with NAME-key are completely ignored. This
709 way system supplied symlinks or permissions gets applied to user-defined
713 Please check your rules setup, if you may need to add OPTIONS="last_rule"
714 to some rules, to keep the old behavior.
716 The rules are read on "remove"-events too. That makes is possible to match
717 with keys that are available on remove (KERNEL, SUBSYSTEM, ID, ENV, ...) to
718 instruct udev to ignore an event (OPTIONS="ignore_device").
719 The new ACTION-key may be used to let a rule act only at a "remove"-event.
721 The new RUN-key supports rule-based execution of programs after device-node
722 handling. This is meant as a general replacement for the dev.d/-directories
723 to give fine grained control over the execution of programs.
725 The %s{}-sysfs format char replacement values are searched at any of the
726 devices in the device chain now, not only at the class-device.
728 We support log priority levels now. The value udev_log in udev.conf is used
729 to determine what is printed to syslog. This makes it possible to
730 run a version with compiled-in debug messages in a production environment
731 which is sometimes needed to find a bug.
732 It is still possible to supress the inclusion of _any_ syslog usage with
733 USE_LOG=false to create the smallest possible binaries if needed.
734 The configured udev_log value can be overridden with the environment variable
739 Possible use of a system-wide klibc:
740 make USE_KLIBC=true KLCC=/usr/bin/klcc all
741 will link against an external klibc and our own version will be ignored.
745 We support an unlimited count of symlinks now.
747 If USE_STATIC=true is passed to a glibc build, we link statically and use
748 a built-in userdb parser to resolve user and group names.
750 The PLACE= key is gone. It can be replaced by an ID= for a long time, because
751 we walk up the chain of physical devices to find a match.
753 The KEY="<value>" format supports '=', '==', '!=,' , '+=' now. This makes it
754 easy to skip certain attribute matches without composing rules with weird
755 character class negations like:
756 KERNEL="[!s][!c][!d]*"
757 this can now be replaced with:
759 The current simple '=' is still supported, and should work as it does today,
760 but existing rules should be converted if possible, to be better readable.
762 We have new ENV{}== key now, to match against a maximum of 5 environment
765 udevstart is its own binary again, because we don't need co carry this araound
766 with every forked event.
