mkimage gains --rootfs-image/--oem-image (raw ext4 matched pair placed into slot A, size-checked fail-closed; slot B keeps the skeleton as a known-good fallback), and stage-1 rc now hands the live devtmpfs to the new root across switch_root — busybox switch_root moves nothing, our skeleton init remounted defensively, but a REAL image's getty opens /dev/console immediately and looped on ENOENT without it. Verified with the 2026-08-24 flare-edge build (rootfs 192M + oem 26M): the image's own rcS chain runs on the 6.18 virt kernel, real daemons start (warden-modbus confirmed running via root shell; the shipped 0.2.4 flared reproduces flare-edge#106 exactly, and S99hciinit reports the issue-#4 btlpm symptom — the VM doubles as a faithful reproducer of known field bugs), and a getty answers on the console. qemu/tests/real-image-boot.sh asserts switch_root + daemon starts + login prompt, credential-free. REAL-IMAGE-BOOT-PASS. Regression sweep after the shared-path changes: OTA-APPLY-PASS, PORTAL-SCENARIO-PASS, UI-SHOT-PASS, boot smoke OK.

# Real-image milestone: boot an ACTUAL flare-edge build (rootfs.img + oem.img
|
|
# matched pair) in the VM on the 6.18 kernel and assert its own init chain
|
|
# reaches multi-user: the vendor rcS runs, real warden daemons start, and a
|
|
# getty answers on the console.
|
|
#
|
|
# Documented caveats (this is a fidelity milestone, not full parity): the
|
|
# RV1106-only init steps degrade on virt (backlight, goodix, npu, the 5.10
|
|
# /oem modules fail vermagic), and binaries older than the flare-edge #106
|
|
# fix reproduce that crash faithfully. Interactive login uses the image's own
|
|
# credentials — deliberately not recorded here.
|
|
#
|
|
# FAILS CLOSED on missing prerequisites.
|
|
#
|
|
# Usage: real-image-boot.sh <zImage> <rootfs.img> <oem.img>
