archinstall's "Copy ISO network configuration", which a user who connected
with iwctl may pick, turns on iwd and systemd-networkd. CoreDesktop then
turns on NetworkManager too, and after a restart two services fight over
the Wi-Fi card. system/wifi.sh disables iwd and systemd-networkd, without
stopping them, when NetworkManager is enabled and isn't set to use iwd
itself. install.sh runs it, and a migration runs it on existing machines.
The README tells users to choose NetworkManager in archinstall.
