README: bump to v1.13.2-k6.12.47-1, list new patches

- Talos version badge: v1.12.4 → v1.13.2
- Image-tag example + upgrade-command example: v1.13.2-k6.12.47-1
- Add patches 0006 (grub EFI upgrade fallback), 0007 (acquire.go STATE
  wait for slow-init eMMC) and 0008 (imager --insecure for Overlay) to
  the patches table
- Note the slow-eMMC tolerance + canonical 3-CP validation in the
  "Reliable in-place upgrades" roadmap row

+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With
+Secondary Licenses under the terms of this version of the License, the

 The official Talos Image Factory does not support CM5 — the mainline kernel lacks CM5 device trees and RP1 driver support. This builder uses the RPi downstream kernel (via [talos-rpi5/talos-builder](https://github.com/talos-rpi5/talos-builder) patches) to produce working CM5 images with our extensions and overclock config.
 
-## What it builds
+## Current versions
 
-- **Installer image** → `docker.io/svrnty/talos-rpi5:<tag>` (for `talosctl upgrade`)
-- **Raw disk image** → Gitea release `metal-arm64.raw.zst` (for eMMC flashing)
+| Component | Version |
+|-----------|---------|
+| Talos Linux | <a href="https://github.com/siderolabs/talos" target="_blank"><img src="https://img.shields.io/badge/talos-v1.13.2-blue?logo=kubernetes&logoColor=white" alt="Talos version"></a> |
+| RPi Kernel | <a href="https://github.com/raspberrypi/linux" target="_blank"><img src="https://img.shields.io/badge/kernel-6.12.47-blue?logo=linux&logoColor=white" alt="Kernel version"></a> |
+| iscsi-tools | <a href="https://github.com/siderolabs/extensions" target="_blank"><img src="https://img.shields.io/badge/iscsi--tools-v0.1.6-blue?logo=docker" alt="iscsi-tools version"></a> |
+| util-linux-tools | <a href="https://github.com/siderolabs/extensions" target="_blank"><img src="https://img.shields.io/badge/util--linux--tools-2.40.4-blue?logo=docker" alt="util-linux-tools version"></a> |
 
-Baked-in config:
-- RPi downstream kernel with CM5/RP1 support
-- Overclock: 2.6GHz (`arm_freq=2600`, `over_voltage_delta=50000`, `arm_boost=1`)
-- Extensions: `iscsi-tools`, `util-linux-tools`
+## Image tags
+
+Release images are published to <a href="https://hub.docker.com/r/svrnty/talos-rpi5" target="_blank"><code>docker.io/svrnty/talos-rpi5</code></a> with the format:
+
+```
+v<talos>-k<kernel>-<revision>
+```
+
+For example: `v1.13.2-k6.12.47-1`
+
+| Segment | Meaning |
+|---------|---------|
+| `v1.13.2` | Upstream Talos Linux version |
+| `k6.12.47` | RPi downstream kernel version |
+| `1` | Build revision (bumped for config/patch changes on the same upstream versions) |
 
 ## Usage
 
-### Building locally (ARM64 host required)

+talosctl upgrade --image docker.io/svrnty/talos-rpi5:v1.13.2-k6.12.47-1 --nodes <node-ip>
 ```
 
-The pipeline runs on the ARM64 self-hosted runner and:
-1. Builds the kernel, overlay, and installer
-2. Pushes the installer image to Docker Hub
-3. Creates a Gitea release with the raw disk image
+In-place upgrades are fully supported. The image includes patches to force GRUB with `--no-nvram` on arm64 (working around the RPi5/CM5 `SetVariableRT` firmware limitation) and to handle the SBC EFI-only disk layout (no separate BOOT partition).
 
-### Upstream update checks
+### What's included
 
-A weekly scheduled workflow checks for new Talos and RPi kernel releases and creates Gitea issues when updates are available.
+- RPi downstream kernel with CM5/RP1 support (4K page size, aligned with upstream Talos)
+- GRUB bootloader with `--no-nvram` for reliable `talosctl upgrade` on RPi5/CM5
+- SBC EFI-only boot layout support (probe, install, revert all fall back to EFI partition when BOOT partition is absent)
+- Fallback to classic bind mounts on kernels without `open_tree` support (Linux <6.15)
+- Overclock: 2.6GHz (`arm_freq=2600`, `over_voltage_delta=50000`, `arm_boost=1`)
+- PCIe Gen 3 enabled for NVMe (~800 MB/s, via `dtparam=pciex1_gen=3` in `config.txt`)
+- Serial console on GPIO UART0 (`dtoverlay=uart0-pi5`, 115200 baud, even parity)
+- Extensions: `iscsi-tools`, `util-linux-tools`

+### Serial console (read-only)
 
-## Runner Setup (Apple Silicon Mac Mini)
+The serial console outputs kernel logs, boot messages, and panic traces over GPIO UART0 (`ttyAMA0`) at 115200 baud with **even parity**. Talos Linux has no interactive shell — the console is **read-only** and cannot accept input.
 
-The build runner needs:
-- Docker Desktop with Buildx (arm64 native)
-- Gitea `act_runner` registered with labels: `self-hosted`, `macOS`, `arm64`
-- Sufficient disk space for kernel builds (~20GB)
+On Pi5/CM5, GPIO 14/15 are not mapped to UART by default (unlike Pi4). The `dtoverlay=uart0-pi5` device tree overlay is required and is applied via `configTxtAppend` (after `disable-bt` and `disable-wifi` — ordering matters).
+
+#### Wiring (Compute Blade)
+
+Connect a **3.3V** USB-to-UART adapter to the front UART header (3-pin: GND, RX, TX). Only two wires are needed for read-only monitoring:
+
+```
+  USB-UART Adapter          Compute Blade (Front UART)
+  ┌──────────────┐          ┌──────────────┐
+  │          GND ├──────────┤ GND          │
+  │           RX ├──────────┤ TX           │
+  │           TX │          │ RX           │
+  └──────────────┘          └──────────────┘
+      3.3V logic              3.3V GPIO
+```
+
+- **Adapter RX** connects to **Blade TX** (adapter receives data from the blade)
+- **GND** to **GND** (common ground reference)
+- Adapter TX is not needed for read-only monitoring (Talos has no shell to send input to)
+
+> **Warning:** CM5 GPIO is **3.3V only**. A 5V logic adapter will crash or damage the board.
+
+Tested with: [USB to TTL Serial Cable (FT232RNL)](https://www.pishop.ca/product/usb-to-ttl-serial-cable-for-raspberry-pi-5-debugging-ft232rnl-chip/) set to 3.3V mode.
+
+#### Reading the console
 
 ```bash
-# Install act_runner via Homebrew

+### Install disk config ignored on SBCs
+
+Talos ignores the `machine.install.disk` config field on SBC platforms. You **must flash the disk image directly** to your target disk (eMMC, SD, NVMe). For NVMe boot, `dd` the metal image to the NVMe drive and configure the EEPROM boot order (`BOOT_ORDER=0xf416`, `PCIE_PROBE=1`).

+## Roadmap
+
+This project targets production-ready Talos clusters on RPi5/CM5 hardware.
+
+| Status | Milestone | Description |
+|--------|-----------|-------------|
+| Tested | **4K page size** | Aligned with upstream Talos kernel config. Reduces memory overhead and improves workload compatibility (Longhorn, jemalloc, F2FS, etc.). |
+| Tested | **Reliable in-place upgrades** | Force GRUB bootloader with `--no-nvram` on arm64, handle SBC EFI-only disk layout, tolerate slow eMMC init on CM5 (waits up to 5 min for STATE before falling back to maintenance). Verified end-to-end via canonical 3-CP rolling upgrade `v1.12.4 → v1.13.2`. |
+| Tested | **Kernel <6.15 compatibility** | Unconditional `open_tree` capability check — falls back to classic bind mounts on RPi downstream kernel 6.12.x. |
+| Tested | **Serial console** | GPIO UART0 (`ttyAMA0`) via `dtoverlay=uart0-pi5`. Read-only output at 115200 baud, even parity. Verified on Compute Blade with FT232RNL adapter. |
+| Tested | **NVMe boot support** | `dd` image to NVMe + set EEPROM `BOOT_ORDER=0xf416` and `PCIE_PROBE=1`. Verified on 1TB Kingston NVMe on Compute Blade. |
+
+## NVMe boot
+
+The kernel has NVMe built-in (`CONFIG_BLK_DEV_NVME=y`), so booting from NVMe should work by flashing the disk image directly and configuring the RPi5/CM5 EEPROM.
+
+### 1. Flash the image to NVMe
+
+Connect the NVMe drive via a USB adapter and flash:
+
+```bash
+zstd -d metal-arm64.raw.zst | sudo dd of=/dev/<nvme-device> bs=4M status=progress
+sync
 ```

-    pkgs/0001-*.patch      # RPi kernel patch
-    talos/0001-*.patch     # Module list patch
+
+### 2. Configure EEPROM boot order
+
+Use `rpiboot` to update the CM5 EEPROM. Clone the usbboot repo and edit the boot config:
+
+```bash
+git clone --depth=1 https://github.com/raspberrypi/usbboot
+cd usbboot && make
+# Edit the EEPROM config for CM5
+cp recovery/boot.conf recovery/boot.conf.bak
 ```
+
+Add or update these values in `recovery/boot.conf`:
+
+```ini
+BOOT_ORDER=0xf416
+PCIE_PROBE=1
+```
+
+Then flash via USB with the CM5 in USB boot mode (hold nRPIBOOT or disable eMMC boot on your carrier board):
+
+```bash
+sudo ./rpiboot -d recovery
+```
+
+`BOOT_ORDER` is read right-to-left: try NVMe (`6`) first, then SD (`1`), then USB (`4`), then restart (`f`). `PCIE_PROBE=1` is required for non-HAT+ NVMe adapters (Compute Blade, most M.2 carrier boards).
+
+### 3. Boot from NVMe
+
+Power on. The RPi firmware should find the boot partition on NVMe, load U-Boot, and boot Talos.
+
+### Optional: enable PCIe Gen 3
+
+PCIe Gen 3 doubles NVMe throughput (~400 MB/s → ~800 MB/s). Not officially certified by Raspberry Pi but stable on most NVMe drives.
+
+**New installs** — PCIe Gen 3 is enabled by default in images built from this repo (`config.txt.append` includes `dtparam=pciex1_gen=3`).
+
+**Existing nodes** — After a `talosctl upgrade`, the overlay rewrites `config.txt` with the baked-in settings (including PCIe Gen 3). If you need to enable it manually on an older image:
+
+1. Power off the node and remove the NVMe drive
+2. Connect via USB adapter and mount the first (EFI) partition
+3. Add to `config.txt` under the `[pi5]` section:
+   ```ini
+   dtparam=pciex1_gen=3
+   ```
+4. Unmount, reinstall the drive, and power on
+
+To verify after boot:
+```bash
+talosctl -n <ip> dmesg | grep -i pcie
+# Look for "Gen 3" in the PCIe link speed output
+```
+
+## Reference architecture
+
+Recommended storage layout for production Talos clusters on CM5 Compute Blade hardware. Each CM5 has a 32GB eMMC and an M.2 NVMe slot.
+
+| Role | Boot disk | NVMe | EEPROM `BOOT_ORDER` | Rationale |
+|------|-----------|------|---------------------|-----------|
+| **Control plane** | NVMe | Talos OS | `0xf416` (NVMe first) | etcd lives on the STATE partition — NVMe gives ~800 MB/s sequential and ~50K random IOPS for fast consensus and snapshot I/O. |
+| **Postgres / storage** | eMMC | Data (`/var/mnt/data`) | `0xf214` (eMMC first) | Talos OS on eMMC keeps `talosctl upgrade` away from the data drive. The full 1TB NVMe is dedicated to database storage via `machine.disks`. |
+| **Compute workers** | eMMC | None | `0xf214` (eMMC first) | Stateless workloads — no local storage needed. eMMC is more than enough for Talos OS (~2.2GB used). |
+
+### Storage configuration
+
+**Control planes** — no extra config needed. Talos installs to the NVMe automatically when it's the boot disk.
+
+**Postgres / storage nodes** — add `machine.disks` to mount the NVMe as a data volume:
+
+```yaml
+machine:
+    disks:
+        - device: /dev/nvme0n1
+          partitions:
+              - mountpoint: /var/mnt/data
+```
+
+Talos automatically partitions, formats (XFS), and mounts the NVMe on first boot. The data persists across `talosctl upgrade` since upgrades only touch the boot disk (eMMC).
+
+**Compute workers** — no storage config needed.
+
+### EEPROM setup
+
+All CM5 modules require `PCIE_PROBE=1` for NVMe detection on Compute Blade (non-HAT+ carrier). Set via `rpiboot`:
+
+```ini
+# recovery/boot.conf
+BOOT_ORDER=0xf416   # NVMe-first (control planes)
+# or
+BOOT_ORDER=0xf214   # eMMC-first (storage/compute workers)
+PCIE_PROBE=1         # always required
+```
+
+### Overclock
+
+All node types share the same overclock config (baked into the image via `config.txt.append`):
+
+```ini
+dtparam=pciex1_gen=3
+dtoverlay=uart0-pi5
+arm_freq=2600
+over_voltage_delta=50000
+arm_boost=1
+```
+
+Verified stable at 44.6°C max under full CPU + memory + disk stress across 10 nodes with Compute Blade heatsinks.

+# Technical Guide
+
+Build infrastructure, CI/CD configuration, and project structure for the Talos CM5 Builder.
+
+## Building locally (ARM64 host required)
+
+```bash
+make checkouts patches   # Clone and patch upstream sources
+make kernel              # Build RPi kernel
+make overlay             # Build SBC overlay
+make installer           # Build installer + disk image
+```
+
+## CI/CD (Gitea Actions)
+
+Push a version tag to trigger an automated build:
+
+```bash
+git tag v1.12.3-k6.12.47-2
+git push origin v1.12.3-k6.12.47-2
+```
+
+The pipeline runs on the ARM64 self-hosted runner and:
+1. Builds the kernel, overlay, and installer
+2. Attaches SBOM attestation (cosign + syft)
+3. Pushes the installer image to Docker Hub
+4. Creates a Gitea release with the raw disk image
+
+### Upstream update checks
+
+A weekly scheduled workflow checks for new Talos and RPi kernel releases and creates Gitea issues when updates are available.

+Date: Mon, 18 May 2026 19:02:29 -0400
+Subject: [PATCH] Replace modules-arm64.txt with RPi 6.12.47 module set
+
+The upstream Talos modules-arm64.txt is the list of kernel modules
+included in the arm64 initramfs. Its entries are computed against
+upstream's mainline kernel build; when Talos is built with the RPi
+downstream kernel (6.12.47), several listed modules either don't
+exist or are gated by upstream-only Kconfig options, causing the
+initramfs install step to fail:
+
+    xargs -a modules-arm64.txt -I {} install -D \
+      usr/lib/modules/${KERNEL_VERSION}/{} ...
+    -> exit 123 (one or more inputs missing)
+
+Replace the list with the intersection of:
+- upstream's "wanted in initramfs" entries
+- modules actually produced by our patched RPi 6.12.47 build
+
+Verified by extracting the kernel image's /usr/lib/modules tree and
+intersecting it with upstream's file. 155 modules survive, covering
+all storage/network/crypto modules needed for headless boot. The 86
+dropped modules are SATA/HID/upstream-only crypto helpers irrelevant
+on RPi5/CM5.

+Subject: [PATCH 3/3] Force GRUB bootloader on arm64
+
+On arm64 platforms like RPi5/CM5, the UEFI firmware (U-Boot) exposes
+/sys/firmware/efi but does not support EFI runtime SetVariable. This
+causes sd-boot to fail when trying to write EFI variables during
+installation/upgrade.
+
+Force GRUB on arm64 in two places:
+
+- NewAuto(): When no existing bootloader is detected, create a GRUB
+  config instead of sd-boot. This handles fresh installs.
+
+- Probe(): When an existing GRUB config is not found, skip sd-boot
+  probing and return a fresh GRUB config. This handles the first
+  upgrade on SBC images that ship with sd-boot UKI files — the
+  upgrade transitions from sd-boot to GRUB automatically.
+
+Combined with the --no-nvram patch and the SBC EFI-only layout patch,
+this enables reliable in-place upgrades via talosctl upgrade on
+RPi5/CM5 hardware, including the first upgrade from a fresh flash.

+Subject: [PATCH 4/4] Fallback to classic bind mounts on kernels without
+ open_tree support
+
+The open_tree syscall on anonymous filesystem file descriptors was added
+in kernel 6.15.0. Talos previously only checked for this capability when
+running in container mode, assuming bare metal always had a sufficiently
+new kernel. However, platforms like RPi5/CM5 use the RPi downstream
+kernel (6.12.x) which lacks this feature, causing shadow bind mount
+failures for /etc files and cascading network initialization failures.
+
+Remove the InContainer() gate so the OpentreeOnAnonymousFS() capability
+check runs on all platforms, enabling the classic (OSRoot) fallback when
+the kernel does not support the newer mount API.

+Subject: [PATCH] Handle missing BOOT partition for GRUB on SBC layouts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On SBC platforms like RPi5/CM5, the disk layout has no separate BOOT
+(XFS) partition — all boot assets (kernel, initramfs, GRUB config,
+EFI bootloader, firmware) reside on a single EFI (VFAT) partition.
+
+The GRUB bootloader probe, install, and revert functions all assumed a
+BOOT partition exists, causing talosctl upgrade to fail with "partition
+with label BOOT not found" on these layouts.
+
+Fix all three code paths to fall back to mounting the EFI partition at
+/boot when the BOOT partition is absent:
+
+- probe.go: Try EFI at /boot as fallback when BOOT is missing, so
+  the upgrade can detect the existing GRUB installation
+- install.go: Probe for BOOT existence before including it in mount
+  specs; when absent, mount EFI at /boot and adjust --efi-directory
+- revert.go: Fall back to EFI at /boot for rollback operations
+
+This enables in-place upgrades via talosctl upgrade on SBC platforms
+that use EFI-only disk layouts.

+Subject: [PATCH] Wait for STATE volume on slow-init disks in config acquire
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On slow-init storage (notably RPi CM5 eMMC, which takes ~2 minutes 13
+seconds from kernel boot to mmc0/CQE-enabled), the config acquire state
+machine's stateDisk step sees STATE in phase=missing during the early
+boot window and immediately transitions to stateEmbedded. With no
+embedded config either, the node falls through to maintenance mode and
+stays there even after the STATE volume later reaches phase=ready —
+the state machine is one-way and never re-enters stateDisk.
+
+Result: in-place upgrades to v1.13.2 on CM5 hardware leave the node in
+maintenance with its on-disk config.yaml intact but unread, until a
+human runs `talosctl apply-config --insecure` to re-feed the same file
+that's already on the STATE filesystem.
+
+This patch makes stateDisk tolerate transient phase=missing for up to
+5 minutes (stateMissingDiskTimeout) before falling through. The outer
+Run loop gets a 5-second ticker so the timeout can fire even when no
+further volume-status events arrive (e.g. truly missing STATE on a
+fresh install). Fast-init hardware sees no change — STATE reaches ready
+within seconds and the existing path runs.
+
+Tested on RPi CM5 (eMMC, 6.12.47 RPi-downstream kernel) — boot path
+that previously dropped to maintenance now waits ~2m15s, sees STATE
+reach ready, and continues to stateDone with the persisted config.

+
+On SBC platforms (RPi5/CM5), the disk layout has no separate BOOT
+partition. During upgrades, the GRUB install code mounts the EFI
+partition at /boot instead of /boot/EFI. The overlay installer was
+always writing to /boot/EFI, causing config.txt and firmware files
+to end up in the wrong subdirectory — invisible to the firmware.
+
+Detect the SBC layout by checking if config.txt already exists at
+/boot/ (indicating EFI is mounted there), and write files to the
+correct location.
