[LAD] Failed to connect to session bus for device reservation

[Winfried Ritsch]

Hello,

On headless embedded computer with Debian I mostly start jackd (jack2) with 
dbus session::

   dbus-run-session jackd -a a -d alsa ...

since I prefer using the debian packages before compiling on those slow 
devices.

'man dbus-launch' says:

[...]
To start a D-Bus session within a text-mode session, do not use dbus-launch. 
Instead, see dbus-run-session(1).
[...]

I put this in a systemd run script with all the ambidecoder and so on stuff I 
need connected.

Any objections to this approach, since I am not really a systemd or dbus guru, 
just got it from man pages.
