The first systemd release of 2023 is here, and it introduces a brand spanking new tool for building Unified Kernel Image (UKI) files.

Fresh versions of systemd appear roughly twice a year, apart from release candidates. We reported on the last version, systemd 252, in November last year. As we said at the time, systemd 252 brought in support for Agent P's new, more secure Linux boot process. Those two stories have details of the UKI boot files and how they work. 

The support and tooling for UKI continues to improve, and one of the headline features in version 253 is a tool for building these unified kernel images, which is called ukify.
