i’m looking to upgrade, but is the 1.2.0 version the first one with the dark coin miner?

Does the dark coin cpu miner included in the installation of 1.20 in the fog_1.2.0.tar\fog_1.2.0\src\ folder get put on the server or all the clients? Is it included in the fog service installer for the clients? Also, where does the destination address point for any found darkcoins?
