Integration / D Bus Interview Questions
What is a D-Bus object path?
A D-Bus object path identifies a specific object exposed by a service on the bus, written in a filesystem-like syntax such as /org/freedesktop/NetworkManager/Devices/3.
It functions purely as an address or namespace, not as a real filesystem location; a service internally maps each path it registers to a handler that knows how to respond to calls on that object. A single service can expose many object paths at once, for example NetworkManager exposing one path per network device it manages.
Object paths are combined with an interface name to fully identify what you're calling: the path says which object, while the interface says which set of methods, signals, and properties you're addressing on that object.
A D-Bus object path is best described as:
A single D-Bus service can expose:
