Even known network filesystems still have a problem. If network
filesystem is mounted on boot, it pulls in network-online.target which
(hopefully) serves as synchronization point on shutdown. If there is no
network filesystem to mount at boot, network-online.target is not
started. If you mount NFS manually later there is nothing to wait for
on shutdown so network could be teared down before filesystem is
