+1. Changes to the Makefile where the parameter "--keyrign" was corrected to "--keyring" in multiple build targets including debian11, debian11-java, debian11-java-slim, debian11-graal, debian11-graal-slim, debian11-corretto, debian11-java-slim-maven, debian11-java-slim-gradle, debian11-graal-slim-maven, and debian11-graal-slim-gradle. This appears to be a typo fix across all Java-related build configurations in the Makefile.
+2. Introduces significant enhancements to the debian/mkimage.sh script, including adding a usage function with detailed documentation, improving error handling for command-line arguments, and fixing the "--keyrign" parameter to "--keyring" to match the Makefile changes. It also adds better validation for required arguments and more descriptive error messages when values are missing. The script now includes comprehensive documentation about its purpose and usage examples.
+3. Shows extensive improvements to the script's functionality and robustness, including adding tracing capabilities, better error handling, and more informative logging. It introduces new helper functions like usage(), die(), warn(), and info() for better user feedback. The script now properly checks for required commands (debootstrap, unzip, trivy) and provides installation instructions if they're missing. It also includes better system checks (Linux OS verification, root privileges check, SELinux status) and implements a more reliable way to handle GPG keys by setting up the correct directory structure and permissions before key import.
+4. Continues the script improvements with better package management, repository configuration, and container setup. It adds proper apt repository configuration in the target system, implements package installation with retries, and includes Docker-specific optimizations. The script now provides clearer output about installed packages and their sizes. It also includes better cleanup procedures and more informative completion messages with clear instructions on how to load and run the resulting Docker image. The output now includes example commands and proper formatting for better readability.

+I need to make several improvements to our Debian image-building scripts. First, fix the typo in the `Makefile` where `--keyrign` is incorrectly used instead of `--keyring` across all build targets, including the standard Debian image and Java variants like `debian11-java`, `debian11-graal`, and `debian11-corretto`. Second, enhance the `debian/mkimage.sh` script to include proper error handling, usage documentation, and command-line argument validation. The script should check for required tools like `debootstrap`, `unzip`, and `trivy`, and provide installation instructions if they're missing. Improve the GPG key setup by ensuring the `/root/.gnupg` directory is properly configured before importing keys. Add structured logging with timestamps, warnings, and informational messages. Implement better package installation with retries and proper cleanup. Finally, include clear instructions at the end on how to load and run the generated Docker image, with example commands for verification. The script should be robust, well-documented, and fail early with meaningful error messages if system requirements aren't met.
