_systemd-networkd_ uses a randomly-generated ID as the DHCP client
identifier by default. On Aimee OS, it is not able to persist this ID
between boots; I think it may derive the value from the machine ID. To
avoid getting a new IP address every boot, we can configure it to use
the MAC address of the device as the DHCP client ID.
We need the Broadcom firmware from the _linux-firmware_ package (and
nothing else). We also need _wpa_supplicant_, to configure the WiFi
connection. Finally, we need to configure _systemd-networkd_ to manage
the network device.
