X11 forwarding with ssh to a system with AFP/CIFS home directories (xauth fails)

I had a user come to me saying they couldn't forward X11 from their home institution to us. I watched them logged in and noticed that xauth was complaining it couldn't lock files. I looked a little deeper and it was that xauth creates a temporary file, then hardlinks to .Xauthority. The problem is that this remote system uses CIFS for home directories (weird huh?).

nookcolor unbrickable (1.0.0 rooted to 1.0.1 unrooted a long journey)

I preface this by saying that I know it's all my fault. I am really impressed by how well Barnes and Noble have built the nookcolor. It's unbrickable, and I've tried (not on purpose) many times now.
