Org fleet configuration consuming NixFleet via nixfleet.lib.mkHost.

Hosts

Host	Platform	Description
krach	x86_64-linux	Hyprland + GNOME, NVIDIA, Bluetooth, impermanent, s33d workstation
ohm	x86_64-linux	GNOME, impermanent, Sabrina's laptop
aether	aarch64-darwin	macOS, Apple Silicon, s33d laptop

Usage

# Deployment (standard NixOS tooling)
sudo nixos-rebuild switch --flake .#krach              # local rebuild
nixos-anywhere --flake .#krach root@192.168.1.50       # fresh install
darwin-rebuild switch --flake .#aether                  # macOS

# nh (colored diffs + progress bars)
nh os switch .                         # NixOS rebuild with diff preview
nh home switch .                       # Home Manager rebuild

# VM helpers
nix run .#spawn-qemu               # launch QEMU VM
nix run .#spawn-qemu -- --persistent -h <host>  # build + install + persistent VM
nix run .#test-vm                  # VM test cycle

# Maintenance
nix fmt                            # format (alejandra via treefmt-nix)
nix flake update secrets           # update secrets
nix flake update nixfleet          # update framework

# Templates
nix flake init -t .#devenv         # scaffold new project with devenv

Secrets

Managed with agenix. Encrypted secrets live in fleet-secrets (private).

nix flake update secrets    # after changing secrets

Adding a Host

1. Add mkHost entry in flake.nix under nixosConfigurations
2. Create modules/hosts/<name>/hardware-configuration.nix and disk-config.nix
3. Deploy: nixos-anywhere --flake .#<name> root@<ip>

Tests and Rust crates live in nixfleet.
