Steps: 1. emerge mpd 2. /etc/init.d/mpd start result: * Caching service dependencies ... [ ok ] * Starting Music Player Daemon ... unable to open db file "/var/lib/mpd/database": No such file or directory can't open db file and using "--no-create-db" command line option try running "/usr/bin/mpd --create-db" expected result: starting the daemon without error
fixed, thanks
