<message>Implement a new API endpoint for cancelling ongoing cloud-init builds, allowing users to request a build cancellation via the dashboard. Update the dashboard UI to include a cancel button that appears during the build process, enhancing user experience by providing control over long-running operations. Modify the build script to check for cancellation requests, ensuring that builds can be stopped gracefully. This feature improves usability and responsiveness in the cloud-init image building workflow.
Enhance the dashboard UI by introducing an optional input field for the image name in the cloud-init build form. Update the API to process the image name, ensuring it is sanitized and included in the build request. Modify the build script to utilize the provided image name, allowing for customized output filenames during the image creation process. This improves user experience by offering more flexibility in naming cloud-init images.
Update the API to support streaming and decompressing of golden images in .img.xz and .img.gz formats on the fly. Modify the cloud-init build process to compress images to .img.xz for size reduction. Revise the dashboard templates to set 'desktop' as the default variant for Raspberry Pi OS builds, improving user experience and clarity in options. Update related scripts to ensure compatibility with the new image handling features.
