#13 NixOS (Minimal Setup)

NixOS (Minimal Setup) is a unique and highly technical Linux distribution that rethinks how a system should be configured, built, and managed. Using the Nix package manager and a purely declarative configuration model, NixOS offers atomic upgrades, reproducibility, and rollback for the entire OS—including the kernel and services. While it’s not the lightest in RAM or boot time, a minimal NixOS install (without a desktop) can be surprisingly efficient and is unmatched in control and consistency.

Why NixOS (Minimal Setup) Performs Well

1. Declarative System Configuration: You define everything in a single config file (configuration.nix), so no background daemons, services, or tools are installed unless you explicitly add them.
2. Atomic Upgrades and Rollbacks: System updates are transactional. If something goes wrong, you can boot into a previous generation—without breaking your setup or reinstalling.
3. Reproducible Builds: Nix ensures that the exact same configuration builds the same system—whether on a laptop, VM, or server—ideal for consistency and clean deployment.
4. Minimal Background Processes: With no GUI and only core services, NixOS minimal setup can run under 200 MB RAM at idle.
5. Fast Startup with Optimized Builds: Services are launched through systemd but can be trimmed down to just SSH, networking, or anything else needed.
6. Unintrusive Package Manager (nix): Does not interfere with system-wide state. You can install packages per-user or system-wide, without polluting the core environment.
7. Profile Switching: You can swap between entire system states like version control, including kernel and configuration—no need to snapshot or backup before upgrades.

NixOS Minimal vs Others (Performance View)

Technical Highlights

1. Nix Store: All installed packages live in /nix/store, isolated and hashed by build inputs—so multiple versions of the same tool can coexist without conflicts.
2. No Broken Systems: Even partial upgrades don’t break your environment—everything is built or rolled back atomically.
3. System as Code: Want a server, firewall, and Nginx in one command? Just declare them in configuration.nix and run nixos-rebuild switch.
4. Rebuild with Confidence: You can safely recompile or rebuild your entire OS state, and nothing touches your currently running system unless the build succeeds.

Final Words

NixOS Minimal Setup is ideal for advanced users who want full control, clean environments, and atomic, reproducible upgrades. It's not as RAM-light as Alpine or as fast-booting as Void, but for server use, dev environments, and power-user systems, it provides unmatched consistency and performance reliability. If you like infrastructure-as-code, Git-based OS management, or zero-downtime rollbacks—NixOS minimal is your playground.

#14 ArchLabs / ArcoLinux / EndeavourOS

ArchLabs, ArcoLinux, and EndeavourOS are all Arch-based Linux distributions that aim to simplify installation while preserving Arch's performance and philosophy. They differ in goals and workflows, but all three keep the Arch foundation, meaning they inherit its speed, rolling updates, and minimal resource usage—with added usability for different types of users.

What Makes These Arch-Based Distros Performance Friendly

1. Lean Core Architecture: All three distros maintain the vanilla Arch kernel and userland, ensuring you're working with a slim, efficient base.
2. Pacman & AUR: Use Arch’s blazing-fast pacman package manager and support AUR for community packages—quick installs and near-universal software availability.
3. Modular Desktop Options: From Openbox and i3 (super lightweight) to full DEs like XFCE, KDE, or GNOME—users choose their performance footprint.
4. Rolling Release: Keeps software up-to-date without needing to reinstall or wait for version bumps.
5. Minimal Preinstalled Software: Especially in ArchLabs and EndeavourOS, installs are clean by default—you only run what you choose.

Distro-Specific Performance Notes

ArchLabs

1. Inspired by BunsenLabs (Debian + Openbox), it defaults to Openbox, i3, or BSPWM.
2. Tiny memory usage (~150–250 MB at idle).
3. Perfect for minimalists and tiling WM fans.
4. Fast and script-driven installer.

ArcoLinux

1. More beginner-friendly with tons of tutorials.
2. Multiple editions: Core (bare minimum), B (builder), and X (full).
3. XFCE or Openbox in Core uses ~300–400 MB RAM.
4. Some overhead from helper scripts and themes but still very light.

EndeavourOS

1. Closer to vanilla Arch than the other two.
2. Lightweight Calamares installer with full control over desktop environment selection.
3. XFCE version uses ~400–500 MB RAM.
4. Very little bloat, fast boot, and clean update experience.

Arch-Based Distros vs Others (Performance View)

Technical Highlights

1. Pacman Is Fast: All three use pacman with parallel downloads and no metadata delay like dnf.
2. Openbox & i3 Are Lightweight: For those choosing Openbox or tiling WMs, these distros easily idle below 250 MB RAM.
3. No systemd Workarounds: All three use systemd just like Arch—keeping boot and service handling fast and modern.
4. Installer Convenience: EndeavourOS uses Calamares, ArchLabs uses AL-Installer, and ArcoLinux offers advanced customization options.

Final Words

All three—ArchLabs, ArcoLinux, and EndeavourOS—offer different paths to a lean, Arch-based system.

1. Go with ArchLabs if you love minimalism and tiling WMs.
2. Choose ArcoLinux if you want learning resources and more hand-holding.
3. Pick EndeavourOS if you want a clean, near-vanilla Arch with graphical install convenience.

All three are lightweight, fast, and flexible—delivering Arch power with better usability.
