Description: The service file shipped with this MPD package forces the User to mpd (the upstream service file does not include that directive). This breaks the "user" option in mpd.conf. Apparently that change was introduced to fix https://bugs.archlinux.org/task/42089, so while it might be necessary it would be nice to document this because `systemctl status` does not show that the service is running as the `mpd` user. It is therefore impossible to figure out why modifying MPDs config file results in permission denied errors.


Additional info:
* package version(s) 0.19.9-3t
* config and/or log files etc.

My /etc/mpd.conf is attached

The output of systemctl status mpd is

Removing the "User" line makes it work again.
