With the generated rebar release I was able to start the application with “/some_path/bin/my_app start -config “/some_other_path/my_app.config” which allowed for dynamic configuration. With rebar3 I don’t seem to have the same behavior, it always uses /some_path/releases/<version>/sys.config included during the release build.
