As discussed on phone: this call appears to log on its own anyway,
there's no point in doing this here again. We really shouldn't log
about errors that happen multiple times.
Hence: just eat up the exit code entirely here, ignore any failures,
don't assign the return value to r, just invoke the function without
caring for the return value. The call logs on its own already, and
what it does should not be reason to fail this early.
