Some checks failed
build image / build (push) Has been cancelled
Validated by running it on the machine, twice, and inspecting the result. Two properties of this laptop rule out the obvious approach, and the script exists mainly to encode them. Its internal UFS reports 4096-byte logical sectors, so the image — built with 512-byte geometry — cannot be dd'd onto it; the GPT header and every partition offset would land in the wrong place. And there are no EFI runtime variables, so efibootmgr cannot register a boot entry and GRUB has to sit at the removable-media path where the firmware looks unprompted. Three things the validation runs caught that review would not have: rsync is not in the image. I had put it in the build container and never in the package list, so the first run died at the copy. It now falls back to tar (--xattrs-include='*', or SELinux labels are silently dropped and the result does not boot), and rsync is in base.pkgs for the progress output. Copying a live root makes tar exit non-zero — files change underneath it, and this machine's clock is wrong besides, so every mtime looks like it is in the future. With pipefail that aborted the install after the root filesystem and before /boot, leaving a half-installed disk that looked plausible. Warning-level exits are now tolerated and only a fatal exit 2 stops the run. systemd-machine-id-setup keeps an existing valid id, and one had just been copied off the stick, so the installed system was a clone. The file is removed first now. Also: msm_dpu probes ~6s in, while the initramfs is still root, and asks for qcom/a630_sqe.fw before the real filesystem carrying it is reachable. It never retries. Adding the Adreno firmware to the initramfs is a few tens of kilobytes. c630-firmware does the same for the DSP blobs once they exist, since dracut rejects install_items globs that match nothing. chrony, because the RTC reads 1970 and nothing was correcting it.

# Pull the model-specific Qualcomm blobs off this machine's Windows partition.

# Fedora ships everything for the C630 that Qualcomm allows to be
|

# redistributed, which covers ath10k WCN3990 (WiFi/Bluetooth) outright. What it
|

# cannot ship is the per-model signed firmware, which is signed against this

# Graphics is the surprising one. The generic Adreno 630 pieces are packaged,

# qcom/sdm850/LENOVO/81JL/qcdxkmsuc850.mbn — and Fedora's generic
|
|
# sdm845/a630_zap.mbn is a different device's file.

If qcom-firmware-extract could not find the Windows partition, mount it by hand
|
|
and point the tool at it:
|
|
|
|
sudo mkdir -p /mnt/windows
|
|
sudo mount /dev/disk/by-partlabel/Windows /mnt/windows # adjust as needed
|
|
sudo qcom-firmware-extract --windows-dir /mnt/windows
|
|
|
|
See docs/firmware.md in the c630 repo for the full file list and the manual
|
|
fallback if the tool does not recognise this model.
