<message>Delete the existing bootstrap.sh script used for cloud-init first boot, as it is no longer needed. Update the bootstrap.sh.example script to provide clearer instructions for users on how to customize and deploy their own bootstrap script, ensuring better guidance for cloud-init integration. These changes streamline the provisioning process and enhance user experience.
<message>Update the _set_golden_from_path function to improve the handling of existing golden image files. Replace the existing unlink logic with a more robust method that safely removes files or broken symlinks using the missing_ok parameter. This change enhances the reliability of the backup upload process by ensuring that stale references are properly cleared before setting a new golden image path.
