It does not imply what you infer, because it explicitly says that the 
file in init.d is mapped to a systemd service unit.  The files in rc.d 
are not used, because systemd does not boot to runlevel 2, 3, 4, or 5.

If you want "network" to start on boot, you would use "systemctl enable 
network".  (You would also want to "systemctl disable NetworkManager")
