openwrt/lib/functions/procd.sh Script __openwrt

The openwrt/lib/functions/procd.sh script will listen to the HotPlug implementation after the/SBIN/PROCD process is started, and when there is a HotPlug event, Hotplug.json will be used to execute/ etc/hotplug.d/the script file that corresponds to the event
