Using Long Term Stable Kernel for the Embedded Products
summary
Claims that LTS delivers thousands of community backports—e.g. 4.9 ≈ 4,800 fixes, 4.4 ≈ 5,600 fixes—making it the practical base for long-lived embedded products. LTSI packages a curated annual LTS tree with shared test results and LTSI yearly tree + Yocto 2.4 integration to reduce in‑house patching. Roadmap targets 4.14 → LTS → LTSI with a June patch window and August release. Production tools discussed include Project Treble separates vendor kernel bits, livepatch (kpatch/kGraft on supported platforms) and dual‑partition + Omaha‑style updates.
