looking inside .bitcoin, the only differences i see btwn the contents of this BCH blockchain and my currently working BTC blockchain, both inside Ubuntu VM's on different machines, are two additional files inside the BTC blockchain; .cookie and bitcoind.pid.  anyone recognize those two and what they are?  are they critical to getting this Node Online?

@HCP:  there is no bitcoin.conf inside my working .bitcoin directory on my BTC blockchain.
