NurRouterOS 0.5.0-dev.10 boot-console correction
Scope and decision
This candidate corrects the installer console and media-discovery defect reproduced from immutable 0.5.0-dev.8. It has not been installed on physical hardware and does not qualify the Dell R630, its storage controller, NICs, throughput or recovery path. No production network, RAID setting or physical disk was changed.
The immutable dev.8 ISO remains unchanged at SHA-256 fa3e65bf037e385c74d220b8ed5eb006f48b70b7c459cfdf92b5f5b494be62a9.
Root cause
The dev.8 GRUB default supplied both console=tty1 and console=ttyS0,115200n8, with ttyS0 last. Kernel messages were visible on VGA, but /dev/console and PID 1 installer input/output were owned by the serial console. The graphical/iDRAC display therefore appeared stuck while the serial console had already reached the target-disk prompt.
During media discovery, init also tried a generic read-only mount after the explicit ISO9660 attempts. On non-media disks, BusyBox/kernel filesystem probing selected F2FS and emitted the visible Magic Mismatch messages. Those diagnostics were a side effect of discovery, not evidence of F2FS corruption and not the reason the prompt was invisible.
Corrections
- The default installer and recovery entries use
console=tty0for graphical/iDRAC operation. - Separate installer and recovery entries use
console=ttyS0,115200n8for serial operation. - Dry-run remains available on the graphical console; unattended operation remains explicitly serial.
- Init prints bounded media-discovery progress, checks optical drives first, then removable block devices, and only mounts candidates as ISO9660.
- The build milestone synchronizes product, appliance, installer and packaged
/etc/nurrouter/product-versionidentities before building.

Dev.9 is preserved but REJECTED: its installer identified itself as dev.9 while its payload version stamp remained dev.8. It must not be installed or published.
Executed verification
| Check | Result | Evidence |
|---|---|---|
| dev.8 graphical USB-style reproduction | PASS | evidence/0.5.0-dev.8/field-console-repro-20261103T120901Z/; VGA shows F2FS messages while serial reaches the disk prompt |
| dev.10 UEFI removable-USB graphical boot | PASS | evidence/0.5.0-dev.10/graphical-usb-uefi-20261103T122238Z/graphical.png; visible media progress and disk prompt |
| dev.10 serial USB media discovery | PASS | evidence/0.5.0-dev.10/serial-usb-20261103T122324Z/serial.log; matching dev.10 identities, /dev/sdb media and disk prompt |
| F2FS diagnostics after correction | PASS | Zero F2FS-fs lines in the serial USB run |
| Target-disk preservation | PASS | Before/after SHA-256 files match; no installer selection or confirmation was sent |
| Packaged product identity | PASS | Rootfs contains 0.5.0-dev.10; installer manifest reports product and installer 0.5.0-dev.10 |
| BIOS graphical optical boot | PASS on dev.9 boot-path-equivalent media | evidence/0.5.0-dev.9/graphical-bios-cd-20261103T121711Z/; dev.9 was later rejected only for payload identity |
| Physical R630 boot/install | NOT RUN | Requires new media transfer and read-only retry; installation still requires exact disk identity and explicit erasure authorization |
Next operator action
Transfer dev.10 without overwriting dev.8, verify its SHA-256, and retry read-only boot only using the default “graphical / iDRAC console” entry. Photograph the visible disk list and run no installation. If a shell is used, collect lsblk -d -o NAME,MODEL,SERIAL,SIZE,TYPE,TRAN,ROTA and lspci -nnk. Installation remains blocked until an empty target disk is identified by model, serial and capacity and separately authorized for erasure.
