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 $modalias is not needed and will be removed from one of +the next udev versions, replace it in all rules with ENV{MODALIAS} or +the sysfs "modalias" value. + +Thanks a lot to Marco for all his help on finding and fixing bugs. + +udev 079 +======== +Let scsi_id request libata drive serial numbers from page 0x80. + +Renamed etc/udev/persistent.rules to persistent-disk.rules and +added /dev/disk/by-name/* for device mapper device names. + +Removed %e from the man page. It never worked reliably outside +of udevstart and udevstart is no longer recommended to use. + +udev 078 +======== +Symlinks are now exported to the event environment. Hopefully it's no +longer needed to run udevinfo from an event process, like it was +mentioned on the hotplug list: + UDEV [1134776873.702967] add@/block/sdb + ... + DEVNAME=/dev/sdb + DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0 + +udev 077 +======== +Fix a problem if udevsend is used as the hotplug handler and tries to use +syslog, which causes a "vc" event loop. 2.6.15 will make udevsend obsolete +and this kind of problems will hopefully go away soon. + +udev 076 +======== +All built-in logic to work around bad sysfs timing is removed with this +version. The need to wait for sysfs files is almost fixed with a kernel +version that doesn't work with this udev version anyway. Until we fix +the timing of the "bus" link creation, the former integrated logic should +be emulated by a rule placed before all other rules: + ACTION=="add", DEVPATH=="/devices/*", ENV{PHYSDEVBUS}=="?*", WAIT_FOR_SYSFS="bus" + +The option "udev_db" does no longer exist. All udev state will be in +/$udev_root/.udev/ now, there is no longer an option to set this +to anything else. +If the init script or something else used this value, just depend on +this hardcoded path. But remember _all_content_ of this directory is +still private to udev and can change at any time. + +Default location for rule sripts and helper programs is now: /lib/udev/. +Everything that is not useful on the commandline should go into this +directory. Some of the helpers in the extras folder are installed there +now. The rules need to be changed, to find the helpers there. + +Also /lib/udev/devices is recommended as a directory where packages or +the user can place real device nodes, which get copied over to /dev at +every boot. This should replace the various solutions with custom config +files. + +Udevsend does no longer start the udev daemon. This must be done with +the init script that prepares /dev on tmpfs and creates the initial nodes, +before starting the daemon. + +udev 075 +======== +Silent a too verbose error logging for the old hotplug.d/ dev.d/ +emulation. + +The copy of klibc is removed. A systemwide installed version of klibc +should be used to build a klibc udev now. + udev 074 ======== NAME="" will not create any nodes, but execute RUN keys. To completely
