We are happy to announce version 13 of osbuild, again one of our regular biweekly releases.

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

• 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.
