Is this the expected behavior? Why does the build succeed if the log shows errors?

Regardless of this, I can still boot the created image.

Generally:

• Does this require a certain base image? For example, with ghcr.io/ublue-os/kinoite-main:latest I get:

error: Could not depsolve transaction; 2 problems detected:
 Problem 1: package kernel-devel-matched-6.2.13-300.fc38.x86_64 requires kernel-core = 6.2.13-300.fc38, but none of the providers can be installed
  - cannot install both kernel-core-6.0.10-300.fc37.x86_64 and kernel-core-6.2.13-300.fc38.x86_64
  - conflicting requests
 Problem 2: package kernel-modules-extra-6.2.13-300.fc38.x86_64 requires kernel-modules-uname-r = 6.2.13-300.fc38.x86_64, but none of the providers can be installed
  - cannot install both kernel-modules-6.0.10-300.fc37.x86_64 and kernel-modules-6.2.13-300.fc38.x86_64
  - conflicting requests

• Are there additional requirements to the kernel such that this works? I've tried with linux-surface without success (see Add example for kernel replacement blue-build/legacy-template#60).

Update: The issues with ublue-os were caused by kmods. I don't think it's a general rpm-ostree issue.
