Hello Wilhelm
First of all I want to thank you for the fast reply on my question!
Please see below where I've tried to answer your questions.
I've changed the runlevel links from S01scanbd to S04scanbd, where dbus has
S02dbus.
It looks like the dbus daemon is writing the system_bus_socket file
nevertheless after scanbd gets started.

scanbd is running as root

I am sorry, no. I've set the variable now in /etc/environment file
Now I can start scanbd in foreground with scanbd -f only
This is the first part of my scanbd.conf

This are the runlevel links
pi at raspberrypi:/etc$ sudo find . -name "*scanbd*" -exec ls -la {} \;

Thank you in advance for your help.
