Overview
Architecture Overview
The bootstrap half of the imaging pipeline. It takes a plain Ubuntu Pi and gets it to the point where the image builder can take over, entirely on its own. That is the clever part, because the process spans several reboots.
Architecture Breakdown
How it works
Core mechanics, failure recovery paths, and system design decisions.
Step 01
Repo staging
Clones the build repo onto an attached external disk rather than the SD card, which keeps the card pristine for imaging.
Step 02
Reboot survival
Installs a login hook so the build picks up again after a reboot. That hook is what makes the run genuinely unattended.
Step 03
Handoff
Hands over to the main image-builder orchestrator once the machine is in a known state.
Key Takeaways
Engineering Highlights
- •Carries straight through the reboots a Pi provisioning run needs
- •Build artifacts stay off the card being imaged
- •Clean handoff to the image builder
- •Integrated as the automation/ unattended bootstrap engine in the unified pi-image-tools suite
