The other day I installed the mpdas<\/a>, which is the audio scrobbler<\/a> for the music player daemon<\/a>. 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<\/a> for writing your own debian-style init-script. I changed it a little and also installed the daemon<\/a> tool, to turn the interactive mpdas program into a daemon. Just run apt-get install daemon<\/tt> to install it. Then put the following file under \/etc\/init.d\/mpdas<\/tt> and run update-rc.d mpdas defaults<\/tt>. Then mpdas will be run automatically upon boot. Oh, one more thing: put your mpdas configuration under \/usr\/local\/etc\/mpdasrc<\/tt> or adjust the DAEMONOPTS<\/tt> in the init script accordingly. <\/p>\n
