Refactor: Optimize GitHub Actions workflows for efficiency
This commit introduces several optimizations to the GitHub Actions workflows to reduce build times and improve overall efficiency. Key changes include: 1. **Pacman Caching (`build.yml`, `validate-build.yaml`):** - Implemented content-aware cache keys for Pacman packages using `hashFiles` on `packages.x86_64`, `bootstrap_packages.x86_64`, and `pacman.conf`. This ensures the cache is used more effectively and invalidated only when relevant package definitions change. 2. **Docker Build Optimization (`dockerfile`):** - Refactored the `dockerfile` to create a much leaner final image. - The `final` stage now only copies the `entrypoint.sh` script, relying on the CI environment to mount the workspace for build files. - This significantly improves Docker layer caching and reduces the final image size. 3. **Release Notes Streamlining (`build.yml`, `release-notes.yml`):** - Consolidated all release note generation logic into `build.yml`. - The `build.yml` workflow now generates a comprehensive changelog, including categorized commit history between releases, in addition to package update information. - The separate `release-notes.yml` workflow has been removed, simplifying the release process. 4. **Validation Enhancement (`validate-build.yaml`):** - Added detailed ISO verification (file count, size, SHA256 checksum) to the `dockerfile-build` matrix leg in `validate-build.yaml`. - This ensures that ISOs produced by the Dockerized build method (the primary method) are validated to the same standards as those from the `direct-build` method. 5. **Conditional Scheduled Execution (`validate-build.yaml`):** - Implemented logic to skip scheduled runs of `validate-build.yaml` if no new commits have been pushed to the `main` branch since the last successful scheduled validation. - This is achieved by using a dedicated git tag (`last-validated-main-sha`) to store the SHA of the last validated commit. - Workflow permissions were updated to allow tag pushing. These changes aim to make the CI/CD processes faster, more resource-efficient, and more robust.
