summary

Modern embedded Linux devices fail mostly from storage wear, unexpected power loss, and bad updates; practical fixes include using an overlay filesystem or RAM tmpfs for noisy logs, sending metrics off-device, and avoiding frequent flash writes that caused Tesla to recall over 100,000 cars in 2021. Use resilient primitives like SQLite with journaling, perform edits via atomic rename, let systemd manage services, and add a hardware or software watchdog to auto-reboot. Mentioned build tools: buildroot and Yakto.
