I guess many of my source subvolumes have the same received_uuid, 
because I created new snapshots from a snapshot that was previously 
received and the received_uuid just did get copied.

I just did a small experiment on another system, created a snapshot from 
a snapshot that previously was received and could confirm that the 
received_uuid does indeed get copied. Is this a problem?
