OS Image Composer 2026.0 Release

Key New Features

Include Packages from Multiple Repositories :
Seamlessly integrate packages from multiple repositories into your target images, supporting both RPM and Debian package formats. This flexibility allows you to leverage diverse software ecosystems within a single, unified workflow.
Package Dependency Visualization:
Gain unprecedented insight into your package relationships with our new graphical dependency visualization tool. Navigate complex package dependencies through intuitive graph charts directly in the GUI, making troubleshooting and optimization more efficient than ever.
Setting Pre-Deployment Configuration:
Streamline your deployment process by embedding configuration settings/binaries directly into target images. Configure system settings, application parameters, and deployment-specific configurations before image boot, ensuring your systems are deployment-ready from first startup.
Intel Open Edge Platform Integration:
Effortlessly incorporate Intel's Open Edge Platform components and AI libraries into your target images. This native integration simplifies the process of building AI-enabled edge solutions with Intel's optimized software stack.
Embedded Software Bill of Materials (SBOM):
Enhance security and compliance with automatic SBOM generation and embedding. Each target image now includes a comprehensive software bill of materials, providing complete visibility into all components for security auditing and compliance requirements.
EMF-Compatible Image Composition:
Expand your deployment options with support for EMF-compatible Ubuntu and EMT OS image generation. This capability ensures broader compatibility across diverse edge computing environments and deployment scenarios.

OS Image Composer Release

Features in this release:

Image composition with Intel specific OOT Kernel packages ​

Seamless enablement of AI SW stacks with Intel AI libraries (including user space) on the OS distro image​

Declarative paradigm: User template driven and multiple OS distro image compositions (including WindRiver eLxr)​

Minimal effort to support new operating system images​

Multi repository support (custom repos)​

Image generation in RAW, ISO, VHD and QCOW2 formats.​

Native handling of Deb and RPM based OS distros​

OS image configuration with user supplied system config files​

Unified Kernel Image with systemd over UEFI BIOS or Legacy BIOS​

Supports generation of immutable OS images (read only rootfs with dm-verity)​

Signed OS image generation using user supplied keys for secure boot​

Package dependency and conflict resolution, caching for consistent and faster composition​

Verbose and filtered logging based on severity enabling easy trouble shooting

Known Issues/Bug Fixes:

Support for Ubuntu OS Image composition being considered based on VBU feedback​

ISO OS Image installation on NVMe and via USB not functional on RPL platform; (Will fix in the next release)​

AI Library Application Face Detection and Recognition Application output video not displayed locally (missing graphics packages, investigating)​

On certain host platforms composition of OS images with dlstreamer are failing due to intermittent network connection issues during package download. Recommended workaround is to reduce the number of workers from 8 to 1 in the top level os-image-composer.yml config file.
