I think tihs is a post-v208 change, but if you manually mount a network
share manually after booting, network-online.target is pulled in as
Wants= and After=. This should make for correct ordering on shutdown.

# mount.cifs //10.0.2.1/pkgs pkg -o defaults,guest,rw
# systemctl show -p After -p Wants $PWD/pkg
Wants=network-online.target system.slice
After=systemd-journald.socket remote-fs-pre.target network.target network-online.target system.slice -.mount
