Get inventory FRU from inventory system path

Hi Andrei,

> What are you trying to achieve?
I am trying to display the system information section in phosphor-webui.
This section would call the 'getServerInfo' function. 
The function would need to using the "/xyz/openbmc_project/inventory/system" path.

Yes, I want to get exactly what EntityManager (or other inventory-related daemon) expose.
But it's null for this dbus path now.

Hi John,

What are you trying to achieve?
The REST API do just a translation to dbus, so you expect to get exactly what EntityManager (or other inventory-related daemon) expose.
And EM expose nothing to /xyz/openbmc_project/inventory/system
