Add Support for Automatic OS Detection in Packer Builders #13538
Description
Packer currently requires users to manually specify several OS-related configuration values such as distribution type, version, architecture, and boot commands, which can be complex and error-prone—especially when working with multiple templates or different Linux distributions. I would like to request a new feature that enables Packer to automatically detect the operating system and version from the provided ISO or boot image, and then apply the appropriate defaults for boot commands and provisioning options. This would simplify template creation, reduce user mistakes, improve build reliability, and make Packer more user-friendly by eliminating the need for lengthy manual boot command definitions.
