Using Open Source Software to Build an Industrial-grade Embedded Linux Platform...
summary
Describes building an industrial embedded Linux stack from bootloader through OTA with concrete tools and targets: choose kernel strategy via LTSI to get decade-long support instead of six-year mainline, use kernelci and automated autotest + LAVA for board deployment, speed builds with icecream, run daily CVE scans and fuzzing plus 24/7 long-term endurance tests, prefer reproducible builds, pick rootfs via Buildroot/Yocto/Debian depending on constraints, and use A/B or RAUC/Mender-style update schemes to ensure fail-safe, signed remote updates.
