Hi,

Yes, sorry, simple as that.

A current network comes over eth0, and the relayed network also comes over
eth0. I thought they were "doing the right thing" but someone came out for
the "local eth0" network and it assigned it in the "relayed eth0" network
pool.

So client network <-> relay agent <-> DHCP server

To handle that you just don't need to do anything other than define the 
subnet(s). If the network (specifically the relay agent) is correctly 
configured then "it just works" and you definitely don't need any shared 
networks or address assignment logic.

Sorry, I really have no idea what that means !
