How to write to /tmp from legato app

I would like my app to access “/tmp” on the file system instead of the apps/writable location. When I create and write to a file in my application to “/tmp” it goes to /legato/systems/current/appsWriteable//tmp rather than /tmp in the fx30s filesystem

The app is not sandboxed. How can I make my apps refer to the filesystem rather than the relative app location?

so, I removed the app, and reinstalled with sandboxed:false and this seems to work now
