How to make the mpdas run as a daemon

The other day I installed the mpdas, which is the audio scrobbler for the music player daemon. Since there’s no debian package for the Raspberry Pi, I compiled mpdas from scratch and installed it. Now I don’t want to run it manually each time the Raspberry Pi boots up. So I found a nice template for writing your own debian-style init-script. I changed it a little and also installed the daemon tool, to turn the interactive mpdas program into a daemon. Just run apt-get install daemon to install it. Then put the following file under /etc/init.d/mpdas and run update-rc.d mpdas defaults. Then mpdas will be run automatically upon boot. Oh, one more thing: put your mpdas configuration under /usr/local/etc/mpdasrc or adjust the DAEMONOPTS in the init script accordingly.

#!/bin/bash
