Download v0.3 release of RAUC

The RAUC team is proud to announce that we've just released RAUC v0.3! Again, we have worked a lot on stability and support for more and more use cases. RAUC now supports pure UEFI-based booting on x86, multiple board variants in the same bundle, intermediate certificates and enhanced feedback from the boot selection layer.

Enhancements

  • Added support for intermediate certificates, improved bundle resigning and certificate information for hooks. This makes it easier to use a multi-level PKI with separate intermediate certificates for development and releases.
  • Added support for image variants, which allow creating a single bundle which supports multiple hardware variants by selecting the matching image from a set contained in the bundle.
  • Added support for redundant booting by using EFI boot entries directly.
  • Added boot information to rauc status
  • Added rauc extract command to extract bundles
  • Support detection of the booted slot by using the UUID= and PARTUUID= kernel options.
  • Improved the status and error output
  • Improved internal error cause propagation

Bug Fixes

  • Fixed boot slot detection for root=<symlink> boot parameters (such as root=/dev/disk/by-path/pci-0000:00:17.0-ata-1-part1)
  • Removed redundant image checksum verification during installation.

Testing

  • Improve robustness and test coverage
  • Use gcc-7 for testing

Documentation

  • Added documentation for intermediate certificates, re-signing bundles, image variants and UEFI support

In its current master branch, RAUC now supports encrypted Bundles. This tutorial will introduce you to the basics of using encryption in RAUC and show how to use it in a simplified Yocto setup with the meta-rauc Layer.


RAUC v1.6 Released

While major changes are about to come, the RAUC v1.6 release already paves the way under the hood. Built-in streaming support will be one of the next features built on top of the 'verity' bundle format in RAUC.
