Lessons Learned: Migrating a Production Platform to Yocto

summary
Migrating a decade-old Debian-based edge fleet to Yocto takes about eight–nine months solo and yields a single flashable image with the application layer baked in, OTA/delta updates via rauc and AB partitions, and support for multiple boards (two targets in this case). The work uses Bitbake, recipes and the do_configure/do_compile/do_install cycle, solves patch reuse with quilt patching, speeds dev feedback with devtool, and keeps sources auto-tracked via AutoRev while catching runtime segfaults through early on-device testing.
