I'm looking for a de-facto set of rules for creating product display nodes when new product entities are created. I'd also like rules that delete and update product display nodes when their associated product entities are deleted / updated.
I'm going to collate those rules I've found in various issue queues and threads. I'd appreciate if anyone could post their rules here too.
Ultimately I think it would be good to have a module which can be used to add the necessary rules automatically.
