The networking panel in the text installer provides the following options:
Automatically – Configures the target system with an automatic network configuration profile (NCP), similar to the Live Media installer's method.
Manually – Selects the DefaultFixed NCP and provides for static IPv4 configuration of one network interface (NIC). The IPv4 default route and IPv6 autoconfiguration are enabled for that NIC. This option also provides for manual configuration of naming services.
None – Selects the DefaultFixed NCP and configures loopback interfaces only.
