Stage-2 init started only warden-flared and warden-modbus from the payload, so every daemon-backed screen (Automation, MikroTik, Mining, RS485, Starlink, Services) sat in its "not running" state on the rig while the bench panel showed the daemons up with nothing attached. It now starts every warden-* daemon it finds in the panel's own S-number order (ai, automation, modbus, mikrotik, asic, starlink, stratum, flared), each with no arguments as start-stop-daemon runs them on the panel. flare-edge tools/rig-pull-daemons.sh copies a panel's static binaries in. Doing that exposed a latent alias: init pointed warden-modbus's /dev/ttyS4 at /dev/ttyS0 whenever ttyS0 existed, and with --ctl that port IS the control channel, so Modbus polls arrived inside the wake reply and the bridge hung. run.sh now always attaches an RS485 pci-serial (a null chardev without --rs485), and init aliases ttyS4 to ttyS1 when warden.ctl is on the cmdline, ttyS0 otherwise. Verified on a boot with all eight daemons: status json reports automation.engine, mikrotik.backend, mining.available and rs485.available true with the Modbus scan sweeping the empty UART; six daemon-backed pages matched screenshots of the bench panel structurally (0/256 cells differ).

# Launch the WardenOS device VM (qemu-system-arm -M virt, single Cortex-A7,

# 256M: the RV1106G3's shape). See qemu/README.md for what this does and does

# not emulate.

# Usage: run.sh --kernel <zImage> [options] [-- <extra qemu args>]
|
|
# --kernel PATH zImage (canonical or virt.fragment variant)
|
|
# --initrd PATH initramfs (default: qemu/out/initramfs.cpio.gz)
|
|
# --disk PATH virtio disk image from mkimage.sh (default: qemu/out/disk.img
|
|
# when present; pass --no-disk for a diskless initramfs boot)
|
|
# --no-disk boot without a disk (initramfs shell/smoke behavior)
|
|
# --slot _a|_b rootfs slot to boot (default _a)
|
|
# --rtc DATE guest RTC base, e.g. 2021-01-01: reproduces the no-RTC
|
|
# "device boots believing 2021" incident class
|
|
# --rs485 SOCK unix socket chardev for the RS485/Modbus bridge
|
|
# (pci-serial: needs the virt.fragment kernel)
|
|
# --ctl SOCK unix socket to warden-ui's debug channel (nav/page/hit),
|
|
# bridged by init from a pci-serial port; the rig-side
|
|
# twin of tools/warden-ctl over SSH on a real panel
|
|
# --watchdog add i6300esb watchdog, reset on expiry (fragment kernel)
|
|
# --qmp SOCK QMP unix socket (screendump, input-send-event, quit)
|
|
# --display MODE off (default, -nographic) | on (gtk window) | headless
|
|
# (virtio-gpu without a window; screendump via --qmp)
