+  This is not necessarily an error (and thus not a subclass of GenericError),

+  should be instantiated with two values. The first one will specify whether an
+  error should returned to the caller, and the second one will be the returned
+  result (either as an error or as a normal result).

+  Examples:
+    # Return a result of "True" to the caller, but quit ganeti afterwards
