How to install

1. Partition the disk a. Mark NixOS partition as nixroot - use ext4 b. Mark additional data partition as data (if applicable) c. Mark swap partition as swap / use swap file d. mark boot partition as nixboot - use fat32 mkfs.fat -F 32 /dev/sdX1

2. Mount the partitions

swapon /dev/disk/by-label swap
mount /dev/disk/by-label/nixos /mnt
mkdir -p /mnt/boot
mount /dev/disk/by-label/nixboot /mnt/boot
mount /dev/disk/by-label/data /mnt/data

3. Generate

nixos-generate-config --root /mnt
nix-env -iA nixos.git
git clone https://github.com/Rutherther/nixos-config /mnt/etc/nixos/config
cp /mnt/etc/nixos/hardware-configuration.nix /mnt/etc/nixos/nixos-config/hosts/<host>

4. Install

cd /mnt/etc/nixos/config
nixos-install --flake .#<host>

5. Finalize a. Before reboot Set root and user password

   chroot /mnt
   passwd root
   passwd ${user}

b. After reboot Install doom-emacs (as user)

``` sh
~/.emacs.d/bin/doom install
~/.emacs.d/bin/doom sync
```
