We are happy to announce version 12 of osbuild, again one of our regular biweekly releases.

This release adds multiple stages and sources for building OSTree-based systems. See samples/f31-ostree-*.json for examples how to use it.

It also drops support for the org.osbuild.dnf source and stage. Please use the rpm stage instead.

Below you can find the official change log, compiled By Christian Kellner. Everyone is encouraged to upgrade!

• The qemu assembler now supports the VHDX image format. This is the preferred format for AWS targets, so it is a natural fit for our assemblers.

• The grub2 stage now disables the legacy compatibility by default. You have to explicitly enable it in the stage options if you require it.

• Additionally, the grub2 stage now also has a uefi.install option to control whether it installs the UEFI configuration from the build tree into the target tree. Furthermore, a new option called write_defaults controls whether default options are written to /etc (enabled by default).

• The dnf stage was removed. The rpm stage fully replaces all its functionality.

• The fedora27 runner is no longer supported. Fedora 30 is the minimum required host version for Fedora systems.

• Add OSTree integration. This includes multiple stages and sources which allow to export osbuild trees as ostree commits, or import ostree commits into an osbuild pipeline:

  • org.osbuild.rpm-ostree: This stage uses rpm-ostree compose to post-process a tree and prepare it for committing to ostree.

  • org.osbuild.ostree.commit: A new assembler that takes a tree that conforms to the ostree layout and turns it into an ostree commit.

  • org.osbuild.ostree: A new source that provides external ostree commits to a pipeline.

  • org.osbuild.ostree: A new stage that takes an ostree commit and prepares the working directory with its content.

• The osbuild binary now has an --output-directory=DIR argument which allows to specify a directory where to put the output of the pipeline assembler. This is optional for now, but will be made mandatory in the future.

• A new stage called org.osbuild.first-boot allows to control the execution of scripts at the first bootup of the generated images.
