[mpich-discuss] open failed for root's mpd conf

[Dave Goodell]

Just to be sure, you are trying to to use a root-started mpd ring as a  
regular user, correct?  If so, make sure that you have a mode 600 file  
named "/etc/mpd.conf" (no leading ".") containing the secret word.

If you are trying to use a regular user-started mpd ring as a regular  
user, then remove "MPD_USE_ROOT_MPD=yes" from your "~/.mpd.conf".
