 security: distrust two Mozilla root CAs 
Blacklist "Comodo AAA Services root" and "emSign ECC Root CA - G3"
so they are left out of /etc/ssl/certs/ca-certificates.crt.

Mozilla already distrusted the Comodo root for serverAuth (it was only
trusted for email), so emSign ECC G3 is the only root this removes for
TLS. Apps that ship their own trust store (NSS in browsers, certifi,
Java cacerts) are not affected.

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.

  • Evaluate Home Manager
