might need a resync with the documentation.

Bus:
  A bus is a named object inside a domain. Clients exchange messages
  over a bus. Multiple buses themselves have no connection to each other;
  messages can only be exchanged on the same bus. The default entry point to
  a bus, where clients establish the connection to, is the "bus" file
  /sys/fs/kdbus/<bus name>/bus.
  Common operating system setups create one "system bus" per system, and one
  "user bus" for every logged-in user. Applications or services may create
   their own private named buses. See section 5 for more details.
