Problem

As I was upgrading from 0.16 to 0.17, stating the Server via systemctl didn't work and the logs were empty:

Later in the journalctl:

Apparently it couldn't find the automatic-backup.json file and also couldn't create it
I then manually created the file and then it worked.

What is the automatic-backup.json file even used for? Never heard anything about it and it isn't getting mentioned in the Changelog or anywhere else as far as I can see.

Expected behaviour and actual behaviour

• Create the File if it doesn't exist yet and don't complain that the file doesn't exist (If possible of course)
• Write the stack-trace into the mesh.log

The config folder needs to be writeable.
