Okay. How can I start my GNU Screen or tmux so that dbus provides
access to systemd? BTW After sending my bugreport I switched from GNU
Screen to tmux.

Currently I start my tmux during boot this way:

/etc/systemd/system/tmux at .service :

----- Clip here ----
[Unit]
Description=tmux
After=network.target

[Service]
#Type=simple

That mytmux.sh is released here:
