| In OpenWrt we commonly use [[docs:techref:ubus|ubus]] for all kinds of communication. It can provide info from various software as well as request various actions. Nevertheless, not every part of OpenWrt has a daemon that can register itself using ''ubus''. For an example ''uci'' and ''opkg'' are command-line tools without any background process running all the time. | In OpenWrt we commonly use [[docs:techref:ubus|ubus]] for all kinds of communication.

| It would be not efficient to write a daemon for every software like this and run them independently. This is why ''rpcd'' was developed. It’s a tiny daemon with support for plugins using trivial API. It loads library ''%%.so%%'' files and calls init function of each of them. | It would be not efficient to write a daemon for every software like this and run them independently.
