systemd-networkd

A modern system service that replaces ifupdown in minimal setups

Configuration location:

/etc/systemd/network/

Wi-Fi setup (conceptually)

You define:

• network config (.network)
• link config (.link)
• and still use wpa_supplicant

Example:

/etc/systemd/network/wlan0.network

[Match]
Name=wlan0

[Network]
DHCP=yes

Then enable:

systemctl enable systemd-networkd
systemctl start systemd-networkd
