The rules file is renamed +to 60-persistent-storage.rules. + +Create persistent path for usb devices. Can be used for all sorts +of devices that can't be distinguished by other properties like +multiple identical keyboards and mice connected to the same box. + +Provide "udevtrigger" program to request events on coldplug. The +shell script is much too slow with thousends of devices. + +udev 087 +======== +Fix persistent disk rules to exclude removable IDE drives. + +Warn if %e, $modalias or MODALIAS is used. + +udev 086 +======== +Fix queue export, which wasn't correct for subsequent add/remove +events for the same device. + +udev 085 +======== +Fix cramfs detection on big endian. + +Make WAIT_FOR_SYSFS usable in "normal" rules and silent if the whole +device goes away. + +udev 084 +======== +If BUS== and SYSFS{}== have been used in the same rule, the sysfs +attributes were only checked at the parent device that matched the +by BUS requested subsystem. Fix it to also look at the device we +received the event for. + +Build variable CROSS has changed to CROSS_COMPILE to match the kernel +build name. + +udev 083 +======== +Fix a bug where NAME="" would prevent RUN from beeing executed. + +RUN="/bin/program" does not longer automatically add the subsystem +as the first parameter. This is from the days of /sbin/hotplug +which is dead now and it's just confusing to need to add a space at +the end of the program name to prevent this. +If you use rules that need the subsystem as the first parameter, +like the old "udev_run_hotlugd" and "udev_run_devd", add the subsystem +to the key like RUN+="/bin/program $env{SUBSYSTEM}". + +udev 082 +======== +The udev man page has moved to udev(7) as it does not describe a command +anymore. The programs udev, udevstart and udevsend are no longer installed +by default and must be copied manually, if they should be installed or +included in a package. + +Fix a bug where "ignore_device" could run earlier collected RUN keys before +the ignore rule was applied. + +More preparation for future sysfs changes. usb_id and scsi_id no longer +depend on a magic order of devices in the /devices chain. Specific devices +should be requested by their subsytem. + +This will always find the scsi parent device without depending on a specific +path position: + dev = sysfs_device_get(devpath); + dev_usb = sysfs_device_get_parent_with_subsystem(dev, "scsi"); + +The "device" link in the current sysfs layout will be automatically +_resolved_ as a parent and in the new sysfs layout it will just _be_ the +parent in the devpath. If a device is requested by it's symlink, like all +class devices in the new sysfs layout will look like, it gets automatically +resolved and substituted with the real devpath and not the symlink path. + +Note: +A similar logic must be applied to _all_ sysfs users, including +scripts, that search along parent devices in sysfs. The explicit use of +the "device" link must be avoided. With the future sysfs layout all +DEVPATH's will start with /devices/ and have a "subsystem" symlink poiting +back to the "class" or the "bus". The layout of the parent devices in +/devices is not necessarily expected to be stable across kernel releases and +searching for parents by their subsystem should make sysfs users tolerant +for changed parent chains. + udev 081 ======== Prepare udev to work with the experimental kernel patch, that moves @@ -150,7 +237,7 @@ udev 069 A bunch of mostly trivial bugfixes.
