By "pull in" I mean making it included in the transaction. Ordering 
dependencies (such as After) have no effect on that. Only requirement
dependencies can pull units into the transaction. Units that are not in 
the transaction cannot influence the ordering of the transaction.
So you need to add "Wants=C.target" somewhere.

The 'restart' action will work the same in both cases.
It's the 'start' action where the difference can be seen. 'start' won't 
do anything if the service is already active.
The 'restart' action first makes the unit stop (thus making sure it is 
inactive) and then start.

In that case adding Wants makes sense.

May I know what package is this exactly? It's possible we may have 
missed something important by talking in the abstract A,B,C,D terms.
