Made a graphical nonrde LiveCD with linux-firmware. Even non-libre wifi and network cards should work.
Guix, Sway, Pre-configured Emacs, NetworkManager(iwd), gparted, cryptsetup, btrfs, dvorak as a second layout and much more are all inside the box.
@abcdw Thank you, thank you and thank YOU! For this GUIX relative noob, you've relieved a great deal of pain, especially around non-free firmware.
And...#Dvorak too! (Learning that right now.)
