    where the bus name is representative of the underlying hardware.

    In the case of MachineContext, the BMC is not gathering data from
    specific hardware, but is instead parsing device-tree nodes for
    context about the hardware OpenBMC is running on.

    Because the VPD data being parsed is coming from device-tree,
    the daemon and matching service name reflect that.

    Because the parsed data represents 'machine context' data,
    the bus name and associated path the daemon writes to
    reflects that instead.
