For the env variable I choose an PATH-like format so currently it is:
"probe1:probe2:...".
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
should look like. If I provide an empty config file lttng seems to not
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?
