Set up systemd-networkd. For single NIC static IP setup, specify the static IP address, gateway address, and DNS server address. For advanced setup, it will copy all configuration files inside the {{ networkd_configs_dir }} to /etc/systemd/network. The configuration file will have permission 640 with owner root and group systemd-network. This is for preventing the leaking of private keys when setting up WireGuard using systemd-networkd.

Tasks

Arch Linux

  • Remove default configuration file created by the [arch_install.sh](arch_install.sh) script.
  • Create a simple static IP configuration (if {{ networkd_configs_dir }} variable is undefined) or copy all configuration files under {{ networkd_configs_dir }} to /etc/systemd/network.

Fedora

  • Install systemd-networkd and enable systemd-resolved.service.
  • Disable NetworkManager.service
  • Create a simple static IP configuration (if {{ networkd_configs_dir }} variable is undefined) or copy all configuration files under {{ networkd_configs_dir }} to /etc/systemd/network.

Debian

  • Install systemd-resolved.service.
  • Remove /etc/network/interfaces configuration.
  • Create a simple static IP configuration (if {{ networkd_configs_dir }} variable is undefined) or copy all configuration files under {{ networkd_configs_dir }} to /etc/systemd/network.
