Não é possível ativar e usar a rede em vez do NetworkManager

Question

Estou tentando implantar o RDO , mas não consigo seguir alguns dos seus /

In case your system is running with NetworkManager, you need to disable it.

Stop and disable NetworkManager:

systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl enable network

Eu posso seguir os dois primeiros comandos sem problemas. No entanto, o terceiro me dá uma resposta que eu não entendo:

#systemctl enable network
network.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig network on
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).

O serviço parece estar inativo:

#systemctl status network.service
network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network)
   Active: failed (Result: exit-code) since Thu 2015-09-10 11:46:50 ICT; 28min ago

De alguma forma, usando #chkconfig network on funciona.
