Wrote this to have my machine instantly go into ethmining when it boots, which should net about $70/month right now. I stop the miner whenever I want to do any work with the GPU myself, or when I boot into Windows for gaming. When I'm done, I can just restart the service or reboot the machine and it'll go right back into mining. Also logs to seashells, so I can monitor it from wherever if I want.

Here's the service file at /lib/systemd/system/ethmine.service:
