How to Run a Lightweight Developer Toolchain on a Trade-Free Linux Distro

Cut the clutter: a fast, private developer toolchain for classrooms

Too many schools and bootcamps juggle fragmented, telemetry-laden tools and bloated containers while students lose time to setup instead of building. If you teach or learn web development, you need a lean, reproducible dev environment that respects privacy and runs on a Mac-like, trade-free Linux distro. This guide shows you, in 2026 terms, how to install VS Code alternatives, Git, and modern container tools like Podman, then tailor the environment for classroom use with reproducible scripts and privacy-first defaults.

The 2026 context: why this matters now

By late 2025 and into 2026 the landscape matured: many educational programs moved toward local, on-device development to reduce cloud costs and preserve student data privacy. Rootless containers and open registries became mainstream, and privacy-focused OSes with Mac-like UIs gained popularity because they remove corporate telemetry while offering polished experiences. For classrooms that run dozens of lab machines, a lightweight, trade-free, Mac-like Linux distro with curated tooling is now a realistic, modern option.

Trends you should know

• Rootless containers (Podman/Buildah) are standard for safe student sandboxes. See security considerations and detection patterns in security checklists.
• Open-source VS Code builds and code-server deployments let you avoid telemetry while keeping VS Code extensions.
• Flatpak and Open VSX are preferred over proprietary app stores for privacy and reproducibility; Open VSX and composable registries are discussed in broader tooling essays like composable UX pipelines.
• Local LLMs and offline code assistants are now practical for classroom help without sending code to third-party APIs — see debates on open-source vs proprietary AI stacks in open-source AI vs proprietary tools.

Overview: the stack we build

We assemble a toolchain that educators can roll out quickly:

• Editor: VSCodium or code-server (VS Code without telemetry)
• Version control: Git with SSH keys and a lightweight self-hosted Git service (Gitea)
• Containers: Podman and Buildah as Docker alternatives (rootless)
• App delivery: Flatpak and Open VSX registry for verified extensions
• Automation: Simple provisioning scripts and an optional Ansible playbook

Step 1 — Prepare the system

Start from a trade-free, Mac-like distro. Many of these are Arch/Manjaro derivatives with Xfce or a macOS-like layout. Commands below include both Arch-family and Debian-family variants so you can adapt to your distro.

Update packages

sudo pacman -Syu        # Arch/Manjaro family
sudo apt update && sudo apt upgrade -y    # Debian/Ubuntu family

Install core utilities

sudo pacman -S --needed git curl wget sudo base-devel    # Arch
sudo apt install -y git curl wget build-essential sudo      # Debian

Enable Flatpak if it isn't present. Flatpak is helpful for distributing cross-distro apps while avoiding vendor stores.

sudo pacman -S flatpak    # Arch
sudo apt install -y flatpak  # Debian

Step 2 — Install a privacy-friendly VS Code

In classrooms we recommend VSCodium (open-source build of VS Code without Microsoft telemetry) or code-server when you want remote browser access. Both work well on trade-free distros and let you use the Open VSX extension registry.

Install VSCodium

Arch-family:

sudo pacman -S vscodium-bin    # via AUR helper like paru or pamac if AUR is enabled

Debian-family (example using Debian package):

wget -qO - https://gitlab.com/paulcarroty/vscodium-deb-rpm-repo/raw/master/pub.gpg | sudo gpg --dearmor -o /usr/share/keyrings/vscodium-archive-keyring.gpg
echo 'deb [signed-by=/usr/share/keyrings/vscodium-archive-keyring.gpg] https://download.vscodium.com/debs vscodium main' | sudo tee /etc/apt/sources.list.d/vscodium.list
sudo apt update && sudo apt install -y codium

Install code-server (optional)

Use code-server when students connect from tablets or Chromebooks to a lab machine. It can be run as a systemd service or inside a rootless container.

curl -fsSL https://code-server.dev/install.sh | sh

Then configure a strong password or use a classroom reverse proxy and mTLS for secure access.

Tip: use Open VSX and extension packs

Open VSX is the open registry for extensions. Configure VSCodium/code-server to use Open VSX so extensions come from an open-source index, which fits the trade-free philosophy.

Step 3 — Git: install, configure, and self-host

Git is non-negotiable. For classroom privacy and reproducibility, set up a central, local Git service such as Gitea which is lightweight and easy to run in a container.

Install Git and basic config

sudo pacman -S git    # Arch
sudo apt install -y git  # Debian

git config --global user.name 'Your Name'
git config --global user.email you@example.com
# optional: enable helpful defaults
git config --global init.defaultBranch main
git config --global core.editor codium

Generate SSH keys for students

ssh-keygen -t ed25519 -C 'student@example.edu'
# copy ~/.ssh/id_ed25519.pub to the Git server

Run Gitea with Podman (rootless)

Below is a minimal Podman command to run Gitea. It avoids Docker, runs rootless for better security, and keeps data in a local directory.

mkdir -p ~/gitea/{data,conf,logs}
podman run -d \
  --name gitea \
  -p 3000:3000 -p 222:22 \
  -v ~/gitea/data:/data \
  gitea/gitea:latest

Open the web installer at http://localhost:3000 and complete setup. For class deployments, preconfigure an admin user and create template repos.

Step 4 — Docker alternatives: Podman, Buildah and LXD

In 2026 the recommended approach for classroom containers is Podman (rootless) plus Buildah for image building. They mimic the Docker CLI while avoiding a central daemon and reducing attack surface. For security and monitoring guidance, see predictive and detection approaches in identity and agent security writeups.

Install Podman

sudo pacman -S podman buildah    # Arch
sudo apt install -y podman buildah  # Debian (ensure backports or proper repo if needed)

Run a rootless container for a Node dev environment

podman pull docker.io/library/node:20-bullseye
podman run --rm -it -p 3000:3000 -v $(pwd):/workspace -w /workspace node:20-bullseye bash
# inside container
npm install
npm run dev

Podman accepts the same Dockerfile and supports podman-compose for multi-container setups similar to docker-compose.

Why choose Podman for classrooms?

• Rootless mode prevents container processes from having root on the host.
• No central daemon reduces the attack surface and simplifies per-user sandboxes.
• Works with systemd for process supervision and resource limits.

Step 5 — Provisioning: automate the student workstation

Manual setup doesn't scale. Use a simple shell script or an Ansible playbook to provision student accounts, install packages, and clone dotfiles.

Example quick provisioning script

#!/bin/bash
# simple script to prepare a student machine
set -e
sudo pacman -S --needed codium git podman flatpak -y
# add user skeleton
cp -r /etc/skel /home/student
chown -R student:student /home/student
# clone starter repo
sudo -u student git clone https://your-gitea.local/starter/starter-project.git /home/student/starter

For repeatable, audited deployments use Ansible and maintain a version-controlled playbook. That lets instructors update tools centrally and push changes to lab images. If you need to staff operations or hand off maintenance, consider hiring ops/infra help described in pieces like hiring guides.

Step 6 — Classroom UX and privacy defaults

Small defaults provide big benefits for teaching:

• Install VSCodium and pre-load a recommended extensions pack (linters, formatter, live server)
• Disable telemetry globally by blocking known telemetry domains at the firewall or using hosts overrides
• Provide a dotfiles repo students can fork so everyone starts with consistent shell, Git hooks, and editor settings
• Use local package caches and mirrors to speed updates and avoid external bandwidth hits

Example editor extensions pack

• Prettier or an open-source formatter
• ESLint
• GitLens or light-weight Git UI
• Live Server for static site labs

Install extensions via CLI so the setup is scriptable. For VSCodium you can use the code CLI to install a preset list.

codium --install-extension ms-vscode.cpptools && codium --install-extension esbenp.prettier-vscode

Step 7 — Offline help and local AI assistants

By 2026 local LLMs and offline code assistants have become practical. For classrooms that cannot send student code to the cloud, containerized, local LLMs are an excellent option. Run these models inside a controlled Podman container and expose a local service that integrates with the editor via an extension.

Offer students an offline help endpoint for hints and code reviews; this keeps data internal and reduces cloud fees.

Troubleshooting and common pitfalls

• Podman permissions: Ensure user is in the correct subuid/subgid range and re-login after editing /etc/subuid and /etc/subgid.
• Flatpak portal errors: Install xdg-desktop-portal packages for the desktop in use so Flatpak apps can access native dialogs. See broader tooling and distribution notes in composable tooling guides.
• Missing extensions: Use Open VSX if marketplace extensions are blocked; some Microsoft extensions require additional steps.
• Slow updates: Set up a local distro mirror or apt/pacman cache via rsync to avoid throttled connections in labs. Advice on local infrastructure and power is available in essays like How to Power a Tech-Heavy Shed.

Security checklist for classroom deployments

1. Run containers in rootless mode and limit resource use with cgroups.
2. Use local Gitea with SSH-only access or enforce HTTPS + mTLS for web UIs.
3. Patch the OS and tooling regularly via a mirrored update server.
4. Use disk encryption on student laptops and role-based accounts on lab machines.
5. Install intrusion detection for shared lab servers and monitor container activity.

Small, reproducible defaults beat ad-hoc setups. In 2026, privacy-friendly, trade-free Linux plus modern rootless containers give classrooms a secure, low-cost platform for teaching real-world development.

Actionable takeaways and quick checklist

• Choose VSCodium or code-server for a telemetry-free editor.
• Install Git and run a local Gitea instance for private class repos.
• Use Podman/Buildah for rootless containers and student sandboxes.
• Automate with scripts or Ansible to scale setups across machines.
• Use Flatpak and Open VSX to distribute apps and extensions reproducibly.
• Consider containerized local LLMs for offline code help in 2026 classrooms.

Next steps: a simple rollout plan

1. Build a reference image on one machine with VSCodium, Git, Podman, and Gitea.
2. Create an automated installer script and a dotfiles repo for students.
3. Test a student workflow: clone, edit, commit, run in a Podman container, and push to Gitea.
4. Iterate: add local LLM aid, extra extensions, or hardware-specific tweaks.

Final notes

Trade-free Linux distros with Mac-like UIs give teachers and learners a polished, privacy-first base. Combined with VSCodium, Git, and rootless containers like Podman, you can run a modern development classroom without vendor lock-in or telemetry. The approach above emphasizes reproducibility, security, and minimal student friction—exactly what educators need in 2026.
