[Pkg-mpd-maintainers] Bug#776306: mpdscribble: Fails to start because of error in pidfile creation

[Marco Solieri]

Package: mpdscribble
Version: 0.22-5
Severity: grave
Justification: renders package unusable

With default configuration the service tries to create its pidfile in 
folder '/var/run/mpdscribble', but such a folder is not created by 
installation script, nor it persists to system reboot. This cause the 
system-wide service to fail to start with the following error.

mpdscribble[359]:
  Failed to create pidfile /var/run/mpdscribble/mpdscribble.pid:
  No such file or directory
mpdscribble.service: main process exited, code=killed, status=5/TRAP
systemd[1]: Unit mpdscribble.service entered failed state.

Obvious (and tested) workarounds include:

1. After each reboot, create the folder '/var/run/mpdscribble' owned by
   mpdscribble:mpdscribble with permissions ug+rwX (~default).
2. Disable pidfile creation, by commenting the corresponding line in
   /etc/mpdscribble.conf .
