The systemd service files we ship in our package are almost vanilla in the sense that the only modifications we do are:

sed '/\[Service\]/a User=mpd' -i /usr/lib/systemd/system/mpd.service
sed '/WantedBy=/c WantedBy=default.target' -i /usr/lib/systemd/{system,user}/mpd.service

However I do remember the ChangeLog for 0.19.20 mentioning "systemd: paranoid security settings." Could you please report your issue upstream? I'd be more than welcome to fix this in our PKGBUILD if it turns out to be a packaging issue but I do not believe it is one. Cheers.

According to upstream, the service file is not intended to be used as a user service. So, there still seems to be a little bit of a packaging issue.

Can we use the old service file for user, or just stop installing the system service as a user one, until upstream may provide its own user service? Thanks.

Oh, right! I had completely forgotten what a hack that user service file was. Let me get rid of it straight away.
