Usability

Improving Error Reporting
● Popup for non-blocking installation errors
● Allowing to fix Registration URL
● Checking mandatory installation packages
● Recovery for broken bootloader configuration
● Checking parameters for serial console
● Kudos to usability team

Reducing Installer Memory Footprint
● We get reports that 512MB is no longer enough
● We again fit into this
● But it also depends on online repositories

Improved Low-vision Accessibility in Installer

Config Files API (CFA)

Quick Intro
● Layered approach
● Precise comment manipulation
● Using existing Augeas lenses
● Contributing to upstream

Smarter Writing
● Keeping whitespaces
● Keeping various empty lines
● Done by marking what is modified

Optimized for Big Files
● Old bug for /etc/hosts
● Better with CFA, but not enough
● Ruby profiler rocks
● Real measurement for /etc/hosts with 10k entries:
○ SCR: 76s
○ CFA (before): 38s
○ CFA (now): 19s

New Usage of CFA
● Originally only Bootloader
● /etc/hosts
● /etc/ntp.conf
● /etc/zypp.conf
● /etc/puppet/puppet.conf
● /etc/salt/*

New Features

Trusted Booting on EFI
● Verifying integrity of all system layers ( bootloader, kernel, ... )
● Thanks to TPM2
● UI feels the same as for TPM1 used for legacy boot

CaaSP and Kubic
● Platform for container orchestration
● Simplified installer
● Many adaptations

New Desktop Selection

Debugger and Profiler Integration
● Environment variables to enable debugger and profiler
● Running debugger if YaST crashes
● On system and also in installation

Weblate for Translators
● YaST switched to openSUSE weblate
● https://l10n.opensuse.org/

New Module for Alternatives
● Result of GSoC
● Kudos to Joaquín Yeray

Salt Integration into Autoinstallation
● Salt is a configuration management system
● Details in a separate talk Adding Salt to AutoYaST by
Imobach González Sosa

New Storage Stack

Separate Presentation
The YaST team is currently redesigning the storage code, down from
the library up to the UI. This will allow many new features, e.g. btrfs
multi device support, encrypted root, bcache and whole disk usage.
