 boot: collect garbage weekly and cap boot entries 
Run nix.gc weekly to delete generations older than 14 days, and limit
lanzaboote to 10 entries so the ESP menu never lists generations whose
store paths have already been collected.

NixOS

Assisted-by: Claude (claude-opus-4-5 → claude-opus-4-6 → claude-opus-4-7 → claude-opus-4-8 → claude-fable-5)

Flake-based NixOS configuration for a ThinkPad P14s Gen 6 (AMD), tracking nixos-unstable.

Highlights

  • Secure Boot via lanzaboote
  • Secrets: sops-nix with age — xray config, WireGuard, SSH keys, private routes/hosts; encrypted files stay out of the repo (only .example structure files are tracked), decrypted to /run/secrets at activation
  • Desktop: GNOME on Wayland, AMD GPU
  • Local LLMs: Ollama with ROCm (gfx1151) + Lemonade for XDNA2 NPU serving via nix-amd-ai
  • Networking: Xray VLESS+Reality with sing-box TUN, WireGuard, WWAN modem
  • Gaming: Steam with gamescope, declarative Flatpaks via nix-flatpak
  • Litecoin Core (MWEB): vendored package build, revived after removal from nixpkgs
  • Power: AMD P-State tuning, zram swap ahead of disk swap

Layout

flake.nix              # inputs and host definition
configuration.nix      # entry point, imports modules
modules/               # one module per concern (boot, desktop, ollama, xray, ...)
secrets/               # sops-encrypted (age) secrets, gitignored; .example files document structure

Usage

sudo nixos-rebuild switch --flake /etc/nixos#meow

Fresh install: restore secrets/ and the age key (/var/lib/sops-nix/key.txt) from out-of-band backup first.
