[MPICH] Please help me ! Error "invalid secretword to root mpd'

[Rusty Lusk]

If you run the mpd's as root, so that multiple users can use the same
mpd ring, then the file mpd is looking for is called mpd.conf (no
leading dot) and is expected to be located in /etc .  This is explained
in the installation guide.
