A feature node can find the index of the next node on the arc using vnet_feature_next(). If there are dependencies between nodes on the same arc, they can be declared using the runs_before or runs_after arrays in the feature node registration. You can find examples of feature node registrations by looking for VNET_FEATURE_INIT. Thanks, -Matt
