For the env variable I choose an PATH-like format so currently it is:
Should I change this to match the config file format then?

I'm looking into this now but its not obvious to me how the config file

have any config options and fails to start. So do you have an example of
a working config file?

I guess because its INI based there should be sections? Which?
