Create a preliminary NEWS entry for the upcoming v13 release. Lots of fixes all over the place, but most of them not worth mentioning for the release. However, we do have some feature improvements as well.

# OSBuild - Build-Pipelines for Operating System Artifacts
|
|
|
|
## CHANGES WITH 13:
|
|
|
|
* Stage `org.osbuild.yum` has been dropped. It has been deprecated for
|
|
some time and `org.osbuild.rpm` provides a better alternative.
|
|
|
|
* XZ compression now utilizes all available CPU cores. This affects all
|
|
stages and assemblers that support XZ compression. It should decrease
|
|
compression times considerably.
|
|
|
|
* `org.osbuild.grub2` now supports referring to file-systems via a label
|
|
additionally to a UUID. This affects all places where an existing
|
|
file-system is referred to. Disk creation still requires a UUID to be
|
|
provided. `org.osbuild.fstab` gained similar support.
|
|
|
|
* RHEL-8.3 is now supported as host system.
|
|
|
|
* The 'libdir' layout in `/usr/lib/osbuild/` has been simplified.
|
|
Distributions are no longer required to create mount anchors during
|
|
installation. Instead, all modules (stages, assemblers, sources, and
|
|
runners) can be copied verbatim from the source tree.
|
|
|
|
* `org.osbuild.grub2` now correctly pads `grubenv` files to 1024 bytes.
|
|
This was not done correctly, previously, and caused other parsers to
|
|
fail.
|
|
|
|
* The containerization via systemd-nspawn was adjusted to support
|
|
running in a container. With sufficient privileges, you can now run
|
|
osbuild pipelines from within a container.

## 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.

## CHANGES WITH 11:
|
|
|
|
* Drop support for legacy input: passing in non-manifest style
|
|
pipelines is now not supported anymore.
|
|
|
|
* Support for specifying an UUID for partitions when using the GPT
|
|
partition layout was added to the org.osbuild.qemu assembler.
|
|
|
|
* Fix a crash in the case the assembler failed, which was caused by
|
|
cleanup up the object while the object was still being written to.
|
|
|
|
* Delay the cleanup of the build tree to after the error checking
|
|
since in the error case there is nothing to clean up and trying
|
|
to do so will lead to crash.
|
|
|
|
* `objectstore.Object` now directly cleans its working tree up, in
|
|
contrast to relying on the implicit cleanup of `TemporaryDirectory`.
|
|
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.

|
## CHANGES WITH 10:
|
|
|
|
* A new man-page `osbuild-manifest(5)` is available, which describes
|
|
the input format of the JSON manifest that `osbuild` expects.
|
|
|
|
* Man-pages can now be built via `make man`. 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.

## 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.
