If DRIVER is used, it will behave like DRIVERS, but an error +is logged. +With the new key names, we have a more consistent and simpler scheme. +We can match the properties of the event device only, with: KERNEL, +SUBSYSTEM, ATTR, DRIVER.

On coldplug, the +events for a lot devices are already bound to a driver, and they will have +that value set. But on hotplug, at the time the kernel creates the device, +it can't know what driver may claim the device after that, therefore +in most cases it will be empty. + +Failed events should now be re-triggered with: + udevtrigger --retry-failed. +Please switch to this command, so we keep the details of the /dev/.udev/failed/ +files private to the udev tools.
