Void Linux on the Raspberry Pi - SD-card install script for Headless use! Only tested on Zero W

create-pi-void-linux.sh

#!/bin/bash
# This makes a readily bootable Voidlinux SD-Card for the raspberrypi
# Sets up some configs, making the Pi connect to wifi and sshd
#
# First boot up takes a very long time (5+ mins even) on a Zero W. Really give it time.
# For remedy on subsequent booting see:
# https://wiki.voidlinux.org/Raspberry_Pi#Enabling_hardware_RNG_device
