 Will launch `/vendor/bin/led_coeffs.bin` as the system user instead of serving the default firmware

+The `devpath` argument may include asterisks (`*`) to match multiple paths. For example, the string
+`/dev/*/red` will match `/dev/leds/red` as well as `/dev/lights/red`. The pattern matching follows

 Ueventd will provide the uevent `DEVPATH` and `FIRMWARE` to this external program on the environment
 via environment variables with the same names. Ueventd will use the string written to stdout as the
 new name of the firmware to load. It will still look for the new firmware in the list of firmware
