Currently I don't know of anyone who runs Inventory Manager and Entity 
Manager together, so you're a bit in untested waters. EntityManager has 
many of the same interfaces as Inventory Manager so that they can both 
work with bmcweb. There is a different fru ipmi command set in 
intel-ipmi-oem that works with fru-device that we use.
