All network mounts configured in fstab will pull in
network-online.target, and are ordered after it.

If you want your service to be started only if there's at least one
remote fs configured, then add WantedBy=network-online.target to your
[Install] section, and Before=network-online.target to your [Unit]
section.

If you want your service to start on *all* boots, regardless whether
there is any remote fs configured in fstan or not -- but if there's a
remote fs configured then before that, then only use
Before=network-online.target in your [Unit] section. (And use
WantedBy=multi-user.target in [Install] as you would for any other
normal service).

Hope that makes sense?
