Description
When a node property value is set to the empty string,
- It is not overriden by a default value set in Rudder's global parameters
- It is not overriden by a
| default="something"in directive parameters
So, as far as replacement mechanisms are concerned, the empty string is not “undefined”.
However, directives using parameters that evaluate to "" cause the generation to fail with an “undefined parameter” message.
This behaviour is inconsistent.
Either "" should be overriden by the default mechanisms, or directives should accept an empty string as a valid parameter value.
