Dependencies or Parent/Child Relationships
Allow devices to be dependent on one another. If a router goes down, the switch behind it will most likely go down or have an error as well.

AS it's currently written, it doesn't support Services as either the dependent or primary. (It could be made to support that, with some extra scripting. Let me know if that's important.)
And yes, you can set the depends_on property at the group level (and then override on devices, if needed.)
