Long story, short question: What should I do to have Wifi available also after power off of Pi without a need for ethernet connection and configuring wifi after each power on?
Orion and the rest of the guys coding RuneAudio have come very far in a short amount of time. Although you could use wifi-menu and then 'netctl enable <wifi-menu profile>', the rest of the code doesn't seem to support wifi only at the moment. Doing that right now will not let you mount your network shares, so an ethernet cable is needed when booting up either way. Failure to do so will delete your entire MPD database.
Please keep in mind that this is a beta, and a fantastic one at that. Keep up the testing, and report any issues. Seeing what the team has accomplished so far gives me great faith, both in terms of audio quality and upcoming features.
