Having followed Zupo's execellent post which was mentioned in a NixOs Weekly, I wondered if it might be possible to setup a rasberry pi3 without the need for a monitor and use wifi rather than an ethernet cable.
There are all ready several blogs that set up raspbian headlessly by the addition of an ssh file in the boot directory and wpa_supplicant.conf in the /etc/wpa_supplicant
directory, but I am unsure how to achieve this in the NixOS way.
Any help appreciated.
