ISO Maker Ubuntu

This tool converts a directory tree into an ISO 9660 image for Ubuntu environments. It supports Joliet and Rock Ridge extensions for cross-platform filename support, and can mark the image as bootable when a boot loader is supplied. Under the hood it uses a standard ISO builder (xorriso acting as mkisofs) to assemble the filesystem, apply metadata, and produce a single ISO file. It also generates a SHA-256 checksum to verify integrity after creation. Use cases include packaging software releases for offline installation, producing bootable USB/DVD media, and archiving project snapshots with verifiable integrity. The tool enforces UTF-8 filenames, optional hidden file inclusion, and volume labeling to match organizational conventions. Advanced options allow boot catalog customization and, if needed, UDF fallback for larger datasets. Outputs are designed for deployment pipelines and distribution channels, ensuring repeatable results across builds. The tool supports deterministic timestamps, preservation of file permissions, and a reproducible build recipe for version control. This results in predictable, auditable media suitable for software distribution, education, and disaster recovery workflows.
