This is from the days of /sbin/hotplug +which is dead now and it's just confusing to need to add space at the +end of the program name to prevent this. If you use rules that +depend on this, like the old "udev_run_hotlugd" and "udev_run_devd", +switch them to: RUN+="/bin/program $env{SUBSYSTEM}", otherwise +they will no longer work as expected. + +udev 082 +======== +The udev man page has moced to udev(7) as it doesnot 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
