Embedded Device

Build a minimal Linux image for IoT and edge devices.

Prompt


Create a minimal Debian embedded image with:

Optimization:
- Minimal package set
- Remove documentation, man pages, locales
- Fast boot (target < 10 seconds)

Features:
- Headless (no desktop)
- SSH for remote access
- Watchdog support

Network:
- NetworkManager
- mDNS/Avahi for discovery
- Static fallback IP

Storage:
- Journal to RAM to reduce writes
- tmpfs for /tmp

Users:
- root (initial setup)
- app (no login shell, for applications)

Packages: systemd, openssh-server, curl, ca-certificates
No compiler toolchain.

Adding Tests

After OpenFactory generates the recipe, add verification tests:


Add tests to verify:
- Boot time under 15 seconds
- Memory usage under 200MB idle
- Watchdog is active
- SSH is accessible
- mDNS discovery works

OpenFactory will add these as automated tests that run after the image builds.
