We are happy to announce version 23 of osbuild. This release makes it possible to build Fedora on RHEL systems.

The Image Builder project builds Fedora and RHEL operating system images, as such its test infrastructure is reliant on RPM package repositories to verify previously succeeding builds do not fail with newer Image Builder updates. It is not unusual for CI systems to require external resources, but in the case of RPM repositories we are suddenly confronted with a moving target: If a test fails, was it our Image Builder modification that broke, or does the RPM repository include broken updates?

We are happy to announce that we released osbuild-composer 22.

In version 15, Image Builder gained support for creating OSTree commits. You can install a Linux system using those OSTree commits by using the Anaconda Installer and its Kickstart functionality. This process is rather involved, with none of the individual parts providing a complete solution yet, so let me walk you through it.
