Yes, I meant copying it. But it seems there's more/other work to do.
Maybe I was right first about you are needing a systemd unit file
instead of this script file. (Sorry, I'm not really a Debian expert,
have my own home-brewn Linux distribution for the Pi.)
You will have to wait until my Pi2 arrives before I can check with
Debian. Or someone else helps you with this.

Okay, then you should notice you are running the bus at 3.3V. Most
onewire chips work reliably at 3.3V but others do not. The DS18B20 do.
What is important, that you are connecting the pullup resistor to +3.3V.
NOT 5V! And you should use 1.2k..1.5k, not the 4.7k which is sometimes
ill-advised.

Ah, then I don't get where the 10.xxx and 05.xxx chips come from.
