# Use GUI: it handles Wifi better!
# Check the devices and it's partitions:
lsblk # to check the device names and sizes
# If under /dev/sdc and mounted:
sudo umount /dev/sdc1
# Put the OS image on the USB stick:
sudo dd if=nixos.iso of=/dev/sdc #
# Derived from:
# https://www.maketecheasier.com/nixos-review/
# https://chris-martin.org/2015/installing-nixos
# First, get an internet connection.
# The easiest way is to start the GUI and use the network manager applet:
systemctl start display-manager
# If the ISO doesn't contain GUI, try getting an internet connection either by using an ethernet cable or using =wpa_supplicant=:
# https://wiki.archlinux.org/index.php/WPA_supplicant
# wpa_supplicant -B -i wlp2s0 -c <(wpa_passphrase SSID PASSPHRASE)
