-# D-Bus objects and "interfaces" section specifies the type of FRU's for which,

-# records will be created for all FRU's of type Board and CPU. For each FRU
-# type, corresponding config JSON's are needed for each record. In the example

-# for FRU of type Board and Board_VINI.json is the config to generate the OEM
-# record (VINI is a record in IBM IPZ VPD format) for FRU of type Board. For all
