remove example rules and put the dev.d stuff into the run_directory folder
The distro rules are the best example you can get and the use of
dev.d/ is no longer recommended.

Programs will get called whenever the -device naming program in the system has either named a new device and -created a /dev node for it, or when a /dev node has been removed from -the system due to a device being removed. - -The directory tree under /etc/dev.d/ dictate which program is run first, -and when some programs will be run or not. The device naming program -calls the programs in the following order: - /etc/dev.d/DEVNAME/*.dev - /etc/dev.d/SUBSYSTEM/*.dev - /etc/dev.d/default/*.dev - -The .dev extension is needed to allow automatic package managers to -deposit backup files in these directories safely. - -The DEVNAME name is the name of the /dev file that has been created, or -for network devices, the name of the newly named network device. This -value, including the /dev path, will also be exported to userspace in -the DEVNAME environment variable. - -The SUBSYSTEM name is the name of the sysfs subsystem that originally -generated the hotplug event that caused the device naming program to -create or remove the /dev node originally.
