You must specify the interface to use, for example `ip=enp1s0:dhcp ip=10.10.10.2::10.10.10.254:255.255.255.0:core0.example.com:enp2s0:none`. +* You can provide multiple DNS servers by adding a `nameserver=` entry for each server, such as `nameserver=1.1.1.1 nameserver=8.8.8.8`. . Press Enter to complete the installation. After {op-system} installs, the system reboots. After the system reboots, it applies the Ignition config file that you
