Prerequisites​

BIOS settings (required)​

  • Disable Secure Boot
  • Enable Linux Boot (Beta) mode
  • Firmware version ≥ 1.66 recommended

Build tools​

podman  just

Quick start​

1. Get a dakota:aarch64 image​

Option A — PR/fork upstream dakota and add aarch64 CI:

# Add dakota-fork/build-aarch64.yml to projectbluefin/dakota workflows
# Then update Containerfile FROM line to your fork's image

Option B — build locally (requires BuildStream):

git clone https://github.com/projectbluefin/dakota
cd dakota
bst --option arch aarch64 build oci/bluefin.bst

2. Build the X13s bootc image​

podman build --platform linux/arm64 -t ghcr.io/tuna-os/dakota-x13s:latest .
podman push ghcr.io/tuna-os/dakota-x13s:latest

3. Build the live ISO​

just iso-sd-boot
# Output: output/x13s-live.iso

4. Flash to USB​

just flash-usb /dev/sdX

5. Boot and install​

  1. Boot from USB on the X13s
  2. GNOME live environment loads with the Dakota installer
  3. Install to NVMe — bootc handles subsequent OTA updates

Upgrading an existing bootc system​

sudo bootc switch ghcr.io/tuna-os/dakota-x13s:latest
sudo reboot

Hardware notes​

What's needed vs stock Dakota​

ComponentMechanism
Qualcomm firmwareExtracted from jlinton/x13s COPR (qcom-firmware)
pd-mapper daemonExtracted from COPR, enabled via systemd
Kernel argsbootc/kargs.d/01-x13s.toml — applied at install time
Module load ordermodules-load.d/x13s.conf — pd-mapper before q6v5_pas
Dracut initrdFirmware blobs included, q6v5_pas excluded from initrd
DTB (live ISO)Extracted from kernel dtb dir, embedded in ESP

Kernel​

Dakota uses the GNOME OS kernel (freedesktop-sdk). As of kernel 6.3+, the SC8280XP SoC is supported upstream. The DTB (sc8280xp-lenovo-thinkpad-x13s.dtb) ships in the kernel's dtb directory.

aarch64 dakota upstream​

The upstream projectbluefin/dakota only publishes x86_64. The dakota-fork/ directory contains the workflow additions needed to build and publish an aarch64 image. Submit as a PR to upstream or maintain a fork.
