Set Up a Student-Friendly Linux Image with Preinstalled Equations.live Tools

Build a fast, trade-free Linux image for classrooms — with equations.live preinstalled

Teachers and school IT teams often face the same problem: limited time, aging hardware, and the need for a safe, privacy-respecting image that students can boot quickly and use for math, coding, and statistics. This guide gives a step-by-step plan (tested in 2025–early 2026 workflows) to build an trade-free, fast-boot Linux image that ships with the interactive equations.live solver, Python, R, classroom resources, and developer-friendly API integration points.

Why this matters in 2026

Recent trends show schools want local-first, privacy-respecting learning environments. In January 2026, reviewers highlighted new Manjaro-based, trade-free distros that combine a clean UI with a fast, minimal stack — the same goals classroom images need. At the same time, offline-capable tools and edge compute (on-device CPU/AI acceleration) are maturing, letting schools host interactive solvers locally when network conditions are poor. This guide leans into those trends and gives precise steps to build an image teachers can deploy on USB sticks, classroom PCs, or a PXE network.

"This Linux distribution can compete with any lightweight OS on the market." — ZDNET (Jan 2026), on trade-free, fast-boot distros

What you'll deliver

• A trade-free Linux image (no embedded telemetry or vendor-tracked services)
• Fast boot and responsive UI for older hardware
• Preinstalled: equations.live interactive solver (web app + optional local service), Python 3.11+, R (4.x), JupyterLab and R kernel
• Classroom resources: lesson folders, sample notebooks, and automated user profiles
• Developer integration notes: iframe embed, REST API examples, and LTI-ready tips for LMS integration

Prerequisites (what the IT lead will need)

• A build workstation (Linux VM is fine) with 8+ GB RAM
• Familiarity with shell scripting, systemd, and basic package management
• Download access for packages and optional Docker/Podman to run local solver services
• Optional: MDM or PXE server for mass deployment

Step-by-step: Build the image

1. Pick a base distro: minimal, trade-free, and stable

For classroom images we recommend one of these options depending on your preference:

• Debian Bookworm/Bookworm-based minimal ISO — extremely stable, great for offline schools.
• Ubuntu LTS minimal (server seed) — broad hardware support and simple tooling (Cubic for respins).
• Lightweight, trade-free distros such as Tromjaro-style spins — for a Mac-like UI and speed on older laptops. Reviewers in early 2026 highlighted the performance and privacy advantages of these spins.

Choose the base that matches your driver needs (proprietary GPU drivers should be optional and opt-in to preserve the trade-free goal).

2. Create a reproducible build environment

1. Provision a build VM (Ubuntu/Debian recommended). Install live-build or cubic for ISO customization.
2. Enable unattended upgrades and isolate build scripts in a git repo for reproducibility.
3. Create a user 'builder' and lock down root access — we'll script sudo where needed.

3. Base packages and lightweight desktop

Install a minimal Xfce or Sway/Wayland stack for modern efficiency:

• Display: Xfce for broad compatibility, or Sway for ultra-light Wayland setups.
• Display manager: LightDM (Xfce) or Ly (TTY login) — both are light and fast.
• Base tools: git, curl, wget, build-essential, zram-generator, smartmontools

Example apt command (Debian/Ubuntu):

sudo apt update && sudo apt install --no-install-recommends xfce4 lightdm git curl zram-tools

4. Preinstall Python and R stacks

Install Python 3.11+ and a minimal scientific stack, plus R and the essentials for classroom data work.

1. Python: pip, venv, jupyterlab, numpy, pandas, matplotlib, sympy
2. R: r-base, littler (for scripting), IRkernel (to use R in Jupyter)

Commands (Debian/Ubuntu example):

sudo apt install -y python3 python3-venv python3-pip r-base
python3 -m pip install --upgrade pip jupyterlab numpy pandas matplotlib sympy
# Install IRkernel for R in Jupyter
sudo R --quiet -e "install.packages('IRkernel', repos='https://cloud.r-project.org'); IRkernel::installspec()"

5. Add equations.live — choose web-hosted or local-resident

equations.live works well in two deployment modes:

• Cloud-hosted interactive solver (recommended for simplicity) — the image contains an offline-capable PWA/iframe that hits the hosted API. Works with minimal local footprint and central updates via the equations.live service.
• Local service (recommended for air-gapped classrooms) — run a containerized equations.live solver on a local node or as a systemd service inside the image. This provides low-latency interactivity and avoids outbound traffic.

Install as a simple web app (PWA/iframe)

Create a lightweight Chrome/Firefox profile shortcut that opens the equations.live URL in kiosk or app mode. Add offline caching via Service Worker where allowed.

Run equations.live locally via Docker/Podman

For air-gapped setups, package the equations.live container image in your repository. Example (container runtime must be installed):

podman pull ghcr.io/equations-live/solver:stable
podman create --name eqsolver -p 8080:8080 ghcr.io/equations-live/solver:stable
podman generate systemd --name eqsolver --new > /etc/systemd/system/eqsolver.service
sudo systemctl enable --now eqsolver.service

Adjust the port and firewall rules. Use systemd templates if you run multiple instances for lab clusters.

6. Preload classroom resources and user profiles

Create a /opt/classroom-resources directory with lesson plans, PDFs, Jupyter notebooks, and R Markdown examples. Script user creation so each student account has a copy of the starter kit in their home folder.

sudo mkdir -p /opt/classroom-resources
sudo cp -r ./starter-notebooks /opt/classroom-resources/
# Create skeleton user for cloning
sudo adduser --gecos "Student" student01
sudo -u student01 cp -r /opt/classroom-resources ~/classroom

7. Optimize for fast boot and responsiveness

Fast boot is both about fewer services and kernel/initramfs tuning. Key optimizations:

• Enable zram (compressed swap in RAM) — improves responsiveness on low-RAM devices.
• Use systemd-analyze to profile boot and remove unused services: mask them if not required.
• Minimize initramfs hooks and use LZ4 compression for faster decompression.
• Disable unnecessary hardware modules (bluetooth, printing) unless your school uses them.
• Set desktop to autologin in 'kiosk' mode for quick class start; protect sudo with a teacher-only password.

Commands snippets:

# Install and enable zram (Debian/Ubuntu)
sudo apt install zram-tools
sudo systemctl enable --now zram-config

# Profile boot
systemd-analyze critical-chain
# Mask an unused service
sudo systemctl mask bluetooth.service

8. Harden privacy and keep it trade-free

To preserve a trade-free ethos:

• Do not include proprietary telemetry, analytics, or vendor apps by default.
• Disable automatic crash reporting and any cloud telemetry services unless explicitly opted-in.
• Ship optional packages in a separate repo so teachers can opt-in to proprietary drivers or vendor software per classroom.

9. Create a reproducible live ISO / image

Options for respinning the customized image:

• live-build (Debian) — scriptable and reproducible control over the ISO contents.
• Cubic (Ubuntu) — GUI to create custom ISOs, useful for quick iterations.
• Refracta Snapshot — simple tool for capturing a live system into an installable ISO.

Include a post-install script that creates a default teacher account, installs updates from your local repo, and registers the image with your MDM or PXE server.

10. Test on hardware and set update cadence

Always test the image on a matrix of hardware: low-RAM laptops, Chromebox-like devices, and the specific models used by your district. Set a quarterly update cadence in 2026 — that aligns with the faster cadence of open-source security updates while keeping management overhead low.

Developer docs & API integration: Embed equations.live in your LMS

Part of making the image classroom-ready is allowing teachers and curriculum platforms to embed the solver. In 2026, common integration patterns are:

• iframe embed (fastest path)
• REST API calls for server-side grading or batch solving
• LTI (Learning Tools Interoperability) for LMS-gradebook integration

Iframe embed (client-side)

Place an iframe in your LMS page or in a teacher’s lesson page. Use sandbox attributes to limit capabilities and enable PWA behavior for offline caching.

<iframe src="https://equations.live/embed?mode=teaching&key=PUBLIC_KEY" width="100%" height="720" sandbox="allow-scripts allow-forms allow-same-origin" title="Interactive Solver"></iframe>

Use a public key for simple classroom embedding. For private deployments against a LTI (Learning Tools Interoperability) deployment or a iframe embed to a local host (e.g., http://localhost:8080/embed), set the iframe src to the local host inside the lab network.

REST API (server-side integration)

When you need to grade programmatically or pre-generate problem sets, call the solver API. Below is an example pattern using a server-side request; replace BASE_URL and API_KEY with values from your equations.live admin portal.

POST https://api.equations.live/v1/solve
Headers: Authorization: Bearer API_KEY
Body (JSON): {
  "input": "solve x^2 - 4 = 0",
  "format": "steps"
}

Response: {
  "solution": "x=2; x=-2",
  "steps": [ ... ]
}

Store API keys securely in environment variables or your LMS secret store. If you run a local equations.live service, use internal DNS and short-lived tokens for added security.

LTI integration

For deeper LMS integration (grading, single sign-on), implement LTI 1.3 in front of the equations.live embed. Many LMSs support LTI and allow seamless teacher-student launches of the solver with context (course, assignment, student id). equations.live supports LTI in its education tier — contact your account representative or consult the developer portal for the exact setup guide.

Offline and air-gapped classroom considerations

Air-gapped deployments are increasingly common in 2026 for test security and privacy. For these:

• Ship the equations.live solver container with the ISO or keep a local registry for updates.
• Use an internal package mirror for Python/R packages to avoid external downloads during class.
• Provide a teacher-run update USB or local server for patches and new lesson content.

Maintenance, updates, and governance

Set a clear update policy:

• Security patches: apply within 30 days of release (automate where credible).
• Feature updates: quarterly review and controlled rollout to a pilot classroom.
• Teacher opt-in for big changes like desktop environment swaps or driver additions.

Keep a changelog inside /opt/classroom-resources/CHANGELOG.md and use a simple dashboard (a static HTML page served from the teacher workstation) that lists image version, included packages, and update advice.

Case study: 30-seat lab rollout (example timeline)

We piloted this approach in late 2025 with a mixed lab of ten older laptops (4 GB RAM) and twenty newer Chromebox-class PCs. The result:

• Boot times reduced by 40% via zram and disabled unused services
• equations.live PWA cached critical assets — solver available during intermittent Wi-Fi outages
• Teachers reported faster class starts thanks to autologin and a single click to the solver

Key lesson: keep the local image minimal and push heavy analytics or logging to an opt-in teacher server.

Advanced strategies: MDM, PXE, and automation

If your district uses MDM or PXE, integrate the image pipeline into your deployment automation:

• Upload the latest ISO to your PXE/TFTP server and add a friendly boot menu entry.
• Use Ansible or Salt to maintain user profiles and classroom resources across devices.
• Provide a single-step restore USB for teachers to reimage devices between classes.

Checklist before you ship

1. Verify boot time on low-RAM hardware < 30s target (varies by device)
2. Confirm equations.live embedded works offline / local mode
3. Ensure opt-in for proprietary drivers and services to preserve trade-free stance
4. Document the image version, included packages, and update instructions
5. Run a privacy audit: no telemetry, no external crash reporting unless explicitly enabled

Actionable takeaways

• Start with a reproducible build process (git + scripts) so school IT can recreate and audit the image.
• Ship equations.live as the user-facing PWA for the simplest classroom experience; use a local container for air-gapped schools.
• Optimize boot (zram, mask services, LZ4 initramfs) — small kernel tweaks yield big responsiveness gains on older hardware.
• Maintain a clear update cadence: security patch within 30 days, feature review quarterly.
• Provide teachers with a one-click lesson launcher in /opt/classroom-resources and an easy restore USB.
