As far as I can see from the MSM docs there are two techniques that can be used to copy content:
1- Blueprints
These represent site roots and offer various customizable rollout configs/actions between source site and copy site.
2- Livecopy
In the docs this is frequently and confusingly used as a synonym for the copy of a blueprint source.
However you can also create a live copy without requiring a blueprint source. (New LIveCopy...)
When creating this sort of live copy one is offered a choice of rollout configs, but as far as I can see, only one of these, 'PushOnModify', makes any sense. I cannot find any way of rolling out a livecopy source to a livecopy structure.
Is my understanding of rollout configs for live copies (not blueprints) correct? And if not, what should it be?
