Automation Folder in Hierarchy - How to / best practices

Hi,

Does anyone have some good advice or links to "how to" / "best practices" when working with Automation Folder in a hierarchy.

Some questions I have:

1. IS Windows ADK required both on Parent and Child NS?

2. If I create Automation Folder on Parent NS will it be replicated to Child NS?

3. If Automation Folder is not replicated do I need to create it on every Child NS? Can this be automated?

4. Is the Automation Folder automatically distributed to All Package Servers? Or does this need to be configured.

Thanks.

Stefan
