Initial Setup #

NixOS (dahlia / kielo) #

1. Boot NixOS installer (minimal ISO recommended)

2. Partition disks and mount at /mnt (host-specific, see nixos/hosts/<host>/hardware.nix)

3. Clone this repo:

   nix-shell -p git
   git clone https://github.com/expede/dots.git /mnt/etc/nixos/dots
   

4. Generate hardware config (optional, compare with existing):

   nixos-generate-config --root /mnt --show-hardware-config
   

5. Install:

   cd /mnt/etc/nixos/dots/nix
   nixos-install --flake .#<hostname>
   

6. After reboot, move dots to home and rebuild:

   sudo mv /etc/nixos/dots ~/Documents/dots
   sudo chown -R $USER:users ~/Documents/dots
   cd ~/Documents/dots/nix
   sudo nixos-rebuild switch --flake .#<hostname>
   

7. Set Fish as default shell:

   chsh -s $(which fish)
   

8. Install Doom Emacs (desktop only):

   git clone --depth 1 https://github.com/doomemacs/doomemacs ~/.config/emacs
   ~/.config/emacs/bin/doom install
   doom sync

rustVersion = "1.90.0";

# Enable cross-compilation targets (darwin, linux-musl, wasm, embedded)
enableCrossTargets = true;
