[Pkg-mpd-maintainers] Bug#835502: Bug#835502: mpd: add systemd user unit for autorun with systemd user-session

[Сергей Процеров (Sergey Protserov)]

Hello! I have tried what you suggested. mpd unit fails at startup with
debian systemd[742]: Failed at step NAMESPACE spawning /usr/bin/mpd: 
Operation not permitted
in journalctl --user

I am using i3-wm which does not launch XDG autostart files. However, as 
I know, one can only enable systemd user unit manually, and one can also 
easily disable XDG autostart applications using his DE's settings manager.

As for arch's unit, here it is: 
https://gist.github.com/anonymous/ad23176c3709ee5dbc36c13bb73ce1b5
It seems to work just fine for me.

Sergey.
