+Use these binaries only if you need backward compatibility with
+older udev versions. The use of /etc/dev.d/ is no longer recommended
+Use explicit udev rules with RUN keys to hook into the processing.
+
+ /etc/dev.d/ + /etc/hotplug.d/ directory multiplexing is completely
+ removed from udev itself and must be emulated by calling small
+ helper binaries provided by these helpers:
+ make EXTRAS=extras/run_directory/
+ will build udev_run_devd and udev_run_hotplugd, which can be called
+ from a rule if needed:
+ RUN+="/sbin/udev_run_hotplugd"
+ The recommended way to handle this is to convert all the calls from
+ the directories to explicit udev rules and get completely rid of the
+ multiplexing. (To catch a ttyUSB event, you now no longer need to
+ fork and exit 300 tty script instances you are not interested in, it
+ is just one rule that matches exactly the device.)
