D-Bus (Desktop Bus) is a simple inter-process communication (IPC) system for software applications to communicate with one another. D-Bus was heavily influenced by KDE2–3's DCOP system and has replaced it in the KDE 4 release; it is supported on Linux, Microsoft Windows and Apple OS X operating systems and is used by Qt 4 and GNOME.

Could not get UID and GID
If you get the following error while starting DBUS:
Failed to start message bus: Could not get UID and GID for username "dbus"
then add the user like so:
# groupadd -g 81 dbus # useradd -c 'System message bus' -u 81 -g dbus -d '/' -s /bin/false dbus
