Software Inventory (Source of Truth)

This document is the canonical software list for the NixOS migration. It consolidates prior notes and recon logs into a deduplicated plan.

Legend:

• NOW (Base boot / day-1) = required for first successful NixOS boot and daily workflow basics
• SOON = useful early, but not required to boot and log in
• LATER = intentionally deferred until after a stable base system
• DEFER (Docker later) = explicitly not installed on base system (will be deployed as containers later)

---

1) NOW (Base boot / day-1)

Desktop / session (Wayland)

• niri (primary compositor)
• greetd + tuigreet (display/login manager)
• xwayland (X11 compatibility where needed)
• xdg-desktop-portal + xdg-desktop-portal-gtk + xdg-desktop-portal-gnome (portals baseline; improves screencast/screen share odds)
• Clipboard:
  • wl-clipboard
• Screenshots (Wayland):
  • grim
  • slurp

Core system services

• NetworkManager
  • Static IPv4 is enforced on Wi-Fi SSID: "Aussie Broadband 8729"
  • Interface: wlp4s2
  • IP: 192.168.20.27/24
  • Gateway: 192.168.20.1
  • DNS: 192.168.20.35, 192.168.20.13
  • Wired enp0s31f6: no static IP required for now (DHCP/unused)
• OpenSSH server (sshd)
• PipeWire audio (Pulse + ALSA) + WirePlumber
• Firewall (NixOS default; open SSH port only)

Terminal / shell

• kitty
• zsh
  • oh-my-zsh
  • powerlevel10k
  • Integrations enabled:
    • atuin
    • fzf
    • zoxide

Core CLI tools (daily essentials)

• git
• neovim
• Search/file tools:
  • ripgrep (rg)
  • fd
• Modern replacements:
  • bat
  • eza
• Convenience:
  • curl
  • wget

---

2) SOON (after base boot is stable)

These are commonly used, easy wins, but not required for “first login”.

Dev tools

• Compilers / build:
  • gcc
  • gnumake
  • pkg-config
• Language toolchains (pick pinned versions later):
  • nodejs
  • python3 (+ python3Packages.pip as needed)
  • go
  • Rust strategy: prefer rustup if you need toolchain flexibility, otherwise rustc/cargo from nixpkgs.

CLI utilities commonly used in the previous setup

• jq
• btop
• lazygit
• zellij
• tealdeer (tldr)
• navi
• yazi
• dua-cli (dua)
• unzip / zip / p7zip
• Clipboard (X11 fallback / mixed):
  • xclip (optional; Wayland-first systems typically rely on wl-clipboard)

Apps from Ubuntu recon (snap list) with Nix equivalents

From logs/04_nixos_recon.log snap list:

• code → vscode (unfree)
• firefox → firefox
• thunderbird → thunderbird
• telegram-desktop → telegram-desktop
• spotify → spotify (unfree)
• nushell → nushell
• mqtt-explorer → mqtt-explorer (verify availability in nixpkgs)
• notepad-plus-plus → consider notepadqq or run via Wine (see “LATER”)

---

3) LATER (deliberately deferred until base is reliable)

Desktop apps / optional GUI

• Google Chrome (unfree) (install once graphics/session is stable)
• LibreOffice
• VLC
• Flameshot
  • Note: Flameshot on Wayland can be quirky; ensure portals + permissions work first.
• Timeshift
  • Note: NixOS typically prefers rollback/snapshots via filesystem tooling (e.g., Btrfs snapshots). Use only if you explicitly want it.

Remote desktop / admin tools

• Tailscale (client)
• RustDesk (service/app)

Networking / diagnostics tools (as needed)

• nmap
• arp-scan / arpwatch
• minicom / screen / cu
• ethtool
• tcpdump

Notepad++ situation

• notepad-plus-plus snap existed on Ubuntu.
  • NixOS options:
    • notepadqq (native)
    • Wine route (more moving parts)
  • Keep this until the base system is stable.

---

4) DEFER (Docker later)

These are explicitly postponed and should NOT be part of the base NixOS install.

• Apprise — DEFER (Docker later)
• Obsidian — DEFER (Docker later)

---

5) AI / Agentic stack (LATER; not part of base boot)

From ai_dev_plan.md and software_to_add.md, intentionally excluded from day-1:

• Orchestration / pipelines:
  • Airflow
  • Windmill
  • Activepieces
• Prototyping:
  • Flowise
• RAG / DB:
  • Chroma
• Crawling:
  • Selenium / Playwright
  • Firecrawl
• Agent frameworks:
  • LangChain / LangGraph
• CLI AI tools:
  • Aider
  • OpenCode
  • Gemini CLI
  • Goose / MCP tooling
• Model routing:
  • OpenRouter

Plan: bring these up later via Docker Compose on top of a stable NixOS base.

---

6) Notes / policies

Secrets policy (hard requirement)

• Do not commit API keys, tokens, WiFi PSKs, certificates, or private keys into git.
• Prefer:
  • ~/.config/environment.d/*.conf (local-only)
  • a secrets manager (e.g. sops-nix) once the base system is stable

Graphics strategy note (pending confirmation)

• Hardware includes Intel HD 630 + NVIDIA Quadro P620.
• Final graphics configuration will depend on which GPU is actually driving the 4 monitors.
