for fresh install from nixos-minimal iso:

• get root, make partitions with fdisk, mount root&boot, cd /mnt
• mkdir etc, cd etc
• nix-shell -p git, git clone https://github.com/graevy/nixos, cd nixos
• nixos-generate-config --root /mnt
• nixos-install --flake .#a
• exit root
• proceed to dotfiles
• if recovering, pull stateful sources: home dir (sops-nix should eventually replace this with a decryption step) /var/lib maybe /etc/NetworkManager maybe
