Running great so far!

I finally gave up with my wonky install last night and did a clean image of raspbian and then installed 0.1.8 on it.
0.1.8a upgraded without issue. (sudo even still works  )

I've intentionally not changed any of the default passwords yet, and tonight I'm going to backup the card before tinkering with the system. I'm happy to share this image as a "plug and play" solution for anyone who's interested. You'll just have to log in and put your own pool information in place of my own.
