Hmm, I hadn't noticed that with iSCSI because a service gets started to
connect to the target so the dependencies can be taken care of there.

Should the remote mount unit be generating a Wants dependency along with
the Before/After to ensure the synchronization point targets are active?
Or would that not work for some reason?
