I'd like to learn about the Hotplug event definition engine. I've studied some documentation and referenced the Acmesh definition, but I still have some questions. I'd like to seriously learn how to write this mechanism. Can anyone offer some help? The data interaction seems to use JSON format, which I don't quite understand. I'm an experienced programmer. Could you provide some suggestions?
OpenWrt's hotplug documentation.
If you mean some other hotplug system you'll need to provide links to be more specific.
