 ====== OpenWrt – operating system architecture ======
-Whereas desktop distributions use [[wp>GLib|glib]]+[[wp>D-Bus|dbus]]+[[wp>udev|udev(part of systemd)]], OpenWrt uses [[docs/techref/libubox]]+[[docs:techref:ubus]]+[[hotplug|hotplug2]].
+Whereas desktop distributions use [[wp>GLib|glib]]+[[wp>D-Bus|dbus]]+[[wp>udev|udev(part of systemd)]], OpenWrt uses [[docs:techref:libubox]]+[[ubus]]+[[docs:techref:procd]].
 This provides some pretty awesome functionality without requiring huge libraries with huge dependencies (*cough* glib).

-==== Dependencies of LuCI2 ====
-The idea for LuCI2 and its different components started a long time ago: [[http://luci.subsignal.org/trac/browser/luci2]]; Code is being developed [[http://nbd.name/gitweb.cgi|here]];
-  * ''[[docs:techref:libubox]]'' (~ 12KiB) is a general purpose library which provides things like an event loop, binary blob message formatting and handling, the Linux linked list implementation, and some JSON helpers. The functions in ''libubox'' are used to write the other software in LuCI2
+==== What's the difference between ubus vs dbus? ====
-  * ''[[docs:techref:ubus]]'' (~ 13KiB) is an RPC daemon similar to D-Bus but with a much friendlier C API
-  * ''[[docs:techref:ubox]]''
-  * ''[[docs:techref:mountd]]''
-  * ''[[docs:techref:rpcd]]''
-  * [[http://www.freedesktop.org/wiki/Software/PulseAudio/FAQ/#index2h3|PulseAudio does not depend on GLib]] and does not seem to depends on D-Bus neither: [[http://www.linuxfromscratch.org/blfs/view/svn/multimedia/pulseaudio.html|LFS]]
-  * [[https://archive.fosdem.org/2013/schedule/event/dist_network/|FOSDEM2013: Can Linux network configuration suck less?]]
-==== What's the difference between ubus and dbus? ====
 ''dbus'' is bloated, its C API is very annoying to use and requires writing large amounts of boilerplate code. In fact, the pure C API is so annoying that its own API documentation states: "If you use this low-level API directly, you're signing up for some pain."
