Version 19 of the Agama installer for openSUSE and SUSE has been released. This release includes major changes in Agama's architectural design, organization of the web interface, and more. We always wanted Agama to follow the schema [...] in which the core of the installer could be controlled through a consistent and simple programming interface (an API, in developers jargon). In that schema, the web-based user interface, the command-line tools and the unattended installation are built on top of that generic API. But previous versions of Agama were full of quirks that didn't allow us to define an API that would match our quality standards as a solid foundation to build a simple but comprehensive installer. Agama 19 represents a quite significant architectural overhaul, needed to leave all those quirks behind and to define mechanisms that can be the cornerstone for any future development. LWN last looked at Agama in September 2025.
