[Pkg-mpd-maintainers] Bug#769951: Bug#769951: mpd: `update-rc.d mpd disable' is not enough to be able to run mpd as normal user

can you have a look what it is that's listening on port 6600? E.g. with

    sudo netstat -lntp

I have an inkling that you may see something like

    tcp6       0      0 :::6600                 :::*                    LISTEN      1/systemd

which would mean that systemd socket activation has gotten in the way of
the recommended per-user set-up. That would make this bug
release-critical, IMO, even though one may ask why the above update-rc.d
command is not effective for systemd socket units...
