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 +/sys/class devices to /sys/devices and /sys/block to /sys/class/block. + +Clarify BUS, ID, $id usage and fix $id behavior. This prepares for +moving the class devices to /sys/devices. + +Thanks again to Marco for help finding a hopefully nice compromise +to make %b simpler and working again. + +udev 080 +======== +Complete removal of libsysfs, replaced by simple helper functions +which are much simpler and a bit faster. The udev daemon operatesentirely +on event parameters and does not use sysfs for simple rules anymore. +Please report any new bugs/problems, that may be caused by this big +change. They will be fixed immediately. + +The enumeration format character '%e' is deprecated and will be +removed sometimes from a future udev version. It never worked correctly +outside of udevstart, so we can't use it with the new parallel +coldplug. A simple enumeration is as useless as the devfs naming +scheme, just get rid of both if you still use it. + +MODALIAS and $modalias is not needed and will be removed from one of +the next udev versions, replace it in all rules with ENV{MODALIAS} or +the sysfs "modalias" value. + +Thanks a lot to Marco for all his help on finding and fixing bugs. + +udev 079 +======== +Let scsi_id request libata drive serial numbers from page 0x80. + +Renamed etc/udev/persistent.rules to persistent-disk.rules and +added /dev/disk/by-name/* for device mapper device names. + +Removed %e from the man page. It never worked reliably outside +of udevstart and udevstart is no longer recommended to use. + +udev 078 +======== +Symlinks are now exported to the event environment. Hopefully it's no +longer needed to run udevinfo from an event process, like it was +mentioned on the hotplug list: + UDEV [1134776873.702967] add@/block/sdb + ... + DEVNAME=/dev/sdb + DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0 + udev 077 ======== Fix a problem if udevsend is used as the hotplug handler and tries to use
