Yes, I should have added After=remote-fs-pre.target to this message. It is 
in the code as well (replacing After=local-fs-pre.target used on 
non-_netdev mounts).

Note that mount units do *not* have a default Wants=remote-fs-pre.target 
or Wants=local-fs-pre.target though. These targets are not automatically 
added to the transaction. They are only added if something *else* pulls 
them in (e.g. for iSCSI you would typically have an iscsi.service with 
Before=remote-fs-pre.target and Wants=remote-fs-pre.target).
