You could also convert backend.py:doBackendSetup to just pass instead of
raise an error, and then get rid of this method entirely. I'd be fine
with that.

What's the point behind using the intermediate _image here? Do you want

I know we talked about this yesterday. Perhaps now is a good time to
also force the fstype in the UI so the user can't accidentally choose
