# OSBuild - Build-Pipelines for Operating System Artifacts ## CHANGES WITH 12: * 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.

One advantage of this is that the custom cleanup code can handle immutable directories, which Python 3 fails to clean up. * Drop custom `os-release` creation from the RHEL 8.2 runner. The issue that made this neccessary got fixed upstream. * Ensure the build tree is always being built even if there are no stages specified. * spec file: Do no generate dependencies for the internal files and add NEWS.md to the documentation section. * The Fedora 30 based aarch64 example was fixed and now builds again.

This supports `SRCDIR` and `BUILDDIR` variables to build out-of-tree. * Temporary objects in the object-store are now created in `.osbuild/tmp/`, rather than in the top-level directory. This should help cleaning up temporary objects after a crash. If no osbuild process is running, the `tmp/` subdirectory should not exist. * The final stage of a build-pipeline is no longer automatically committed. You must pass checkpoints via `--checkpoint` to commit anything to the store. * Improve curl timeout handling. This should improve osbuild behavior with slow or bad mirrors and make sure operations are retried correctly, or time-out if no progress is made. Contributions from: Christian Kellner, David Rheinsberg, Lars Karlitski, Major Hayden, Tom Gundersen - Berlin, 2020-03-18 ## CHANGES WITH 9: * The last pipeline stage is no longer automatically committed to the store. This used to be a special case to make things work, but it has now been properly fixed. From now on, if you want a stage committed to the store, you need to pass a `--checkpoint` option for the stage. * The runner for the host system is now auto-detected. The `runners/org.osbuild.default` symlink is now longer required (nor supported). * A generic runner named `org.osbuild.linux` was added. This runner uses the default value of `ID` in `/etc/os-release`. That is, if the local OS cannot be detected, or if no `os-release` file is provided, this is the fallback runner that is used. This runner only performs the bare minimum of initialization. It is enough to run the most basic stages on all systems we tested. * On Archlinux, the generic runner will now be used. * A new runner for RHEL-8.1 is available. * The JSON input to `osbuild` is now a monolithic manifest format which contains all build information. For now, this means the input manifest can contain a `pipeline:` key with the pipeline definition, as well as a `sources:` key with external source definitions previously passed via `--sources`. The old input format is still supported, but will be dropped in the next release. * The osbuild sources now come with a man-page `osbuild(1)`. Further pages will follow in the future.
