Rock64 - Headless Setup?

[SirRyanTheGeek]

I have the following on one of my systems

Code:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
   address 192.168.0.100
   netmask 255.255.255.0
   gateway 192.168.0.1
   wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and in /etc/wpa_supplicant/wpa_supplicant.conf

Code:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="ssid"
    psk="password"
}

That first piece of code - where it references the supplicant file - where does that live? Thanks!
