Systemd service order

I rebooted a system and suddenly noticed I could not ssh into it anymore, puzzled, went to it and found that for some reason eth0 was down, but the netcfg.service had managed to put the loopback up. So systemctl restart netcfg and everything came back normal. Then a thought occured to me, these services are not ordered the way I would have ordered my daemons, so I tried to do that:

This should force network.target-> shorewall.service -> netcfg.service -> sshd.service always and forever right? If not how would I do that? Anything potentially wrong with this?
