The YaST development sprints have brought tons of improvements to openSUSE Leap 42.3. The YaST community has been working hard to improve usability and continues to add new tools and modules in Tumbleweed and Leap. The list of improvements include extending the ability to configure and use Trusted Boot also to EFI systems, new possibilities for network installation, enhancements in the YaST partitioner and better integration with Systemd services.
The most visible change is the revamped desktop selection screen in the installer, that offers a more fair playground for all graphical environments beyond KDE and GNOME. The installer no longer offers a predefined selection of "secondary" desktops environments, but relies on the existing patterns created and maintained by the enthusiasts of every graphical environment. So the "those who do, decide" principle now also drives the selection of available desktops.
AutoYaST is now more robust, powerful and friendly than ever. Apart from faster installation in many situations and better reporting of the adjustments automatically performed to the partition sizes, the management of services have been moved to the first AutoYaST stage, which opens the door to many new possibilities for more flexible unattended scenarios.
The new jewel of the AutoYaST crown is its brand new integration with SaltStack and other configuration management systems introduced by the new addition to the Leap family: the yast2-configuration-manager package. Now AutoYaST can take care of the system installation (partitioning, network setup, etc.) and then delegate the system configuration to one of those widely used external tools.
