As an alternative to the likes of the Pungi tool, Kurchu is a newer project within the CentOS/Fedora space for assembling content collections or ISO images of Linux distribution builds. Kurchu is already seeing use by the CentOS Hyperscale SIG for assembling their images while additional functionality continues to be worked on for those wanting to craft their own Fedora/CentOS install images.

The Kurchu project is designed as a declarative way to create composes rather than the Pungi tool method of programmatically constructing collections of artifacts using custom scripts.

Kurchu breaks down the assembly process into gather, compile, and furnish phases for building operating system images. Right now all of the Kurchu basics are implemented and it's possible to create working images. The CentOS Hyperscale SIG began using Kurchu in April for their CentOS Stream 9 and 10 derived collections.

Kurchu is working toward its version 1.0 release and is being developed via [1]GitLab .

More details on the Kurchu tool via the [2]CentOS blog .

In other CentOS news from the past few days, the CentOS project also [3]announced Quokka as the project's mascot. Quokka is the CentOS mascot moving forward but apparently had been a thought for many years... Not to be confused with Ubuntu 25.10 that is [4]codenamed the Questing Quokka .
