VITAL — Do Not Remove

These are the backbone. Without them, the system does not boot, authenticate, update, or connect.

Package	Why
base	Base system files. Removing this breaks everything.
base-devel	Build toolchain (gcc, make, etc.). Needed for AUR and from-source work.
linux-cachyos + headers	Custom CachyOS kernel with BORE scheduler. Boot-critical.
linux-cachyos-lts + headers	LTS fallback kernel. Boot-critical redundancy.
linux-firmware	Hardware firmware blobs. WiFi, GPU, NIC will fail without.
amd-ucode	AMD CPU microcode updates. Security + stability.
nvidia-580xx-dkms + utils + settings + opencl	GPU driver stack. Display + CUDA + ML workloads.
lib32-nvidia-580xx-utils + lib32-vulkan-*	32-bit compatibility for GPU (Steam, Wine).
mkinitcpio	Initramfs generation. Boot-critical.
efibootmgr + efitools	EFI boot entry management.
limine + limine-mkinitcpio-hook + limine-snapper-sync	Your bootloader + snapper rollback integration.
device-mapper + lvm2 + cryptsetup	Block device layer. LUKS + LVM.
btrfs-progs + snapper	Filesystem tools + snapshot management.
networkmanager + iwd	Network connectivity.
openssh	Remote access.
sudo	Privilege escalation.
iptables	Firewall backend.
pacman + pacman-contrib + paru + yay + aurutils	Package management. Without these you cannot install anything.
systemd (via base)	Init system. Implicit but critical.
pipewire + wireplumber + alsa-*	Audio stack.
mesa (via base / plasma)	OpenGL/Vulkan for AMD iGPU fallback.
noto-fonts + noto-fonts-cjk + noto-fonts-emoji	System font coverage. Broken UI without.

Unchecked / Unknown

These weren't in the package list or I couldn't identify them. Verify manually:

• go (Golang) — check with which go
• java / jdk / jre — check with java -version
• scala / kotlin / clojure — JVM languages
• haskell / ghc / stack — check with ghc --version
• dart / flutter — check with flutter --version
• elixir / erlang — check with elixir --version
• ruby / gem — check with ruby --version
• perl (listed but minimal) — usually system dependency
• php — check with php --version
• lua — check with lua -v
• R — check with R --version
• nix — check with nix --version
• guix — check with guix --version
• flatpak — check with flatpak --version
• appimageLauncher / appimaged — AppImage integration
• snapd — check with snap --version
• tlp / auto-cpufreq — power management alternatives
• fprintd — fingerprint reader

• android-studio — Android dev
• unityhub / godot — Game engines
• unreal-engine — (unlikely, but check)

---

Python Environment Note

You have no user pip packages (pip list --user returned empty). This is good — it means Python tools are either:

1. System packages (python-* from pacman)
2. Managed by uv (.local/share/uv/python/...)
3. In virtual environments (not shown)

If you use uv or conda, those environments are separate and not counted here.

---

Rust/Cargo Note

Cargo-installed binaries:

• aichat v0.30.0 — CLI chat tool (redundant with aichat-ng-bin pacman package?)
• wasm-pack v0.14.0 — WebAssembly build tool

Keep wasm-pack if you do Rust→WASM. aichat may duplicate system package.

Summary by Category

Category	Count	Approx Size
VITAL	~40	~2GB (kernel, drivers, base)
NEEDED	~50	~3GB (toolchains, DE, browsers, comms)
USEFUL	~150	~4GB (apps, devtools, media)
IF YOU MUST	~150	~3GB (heavy/duplicate/niche)
Total	391	~12-15GB

Potential savings from aggressive cleanup: 3-5GB by removing duplicates and heavy niche tools.
