After some time of silent work (our previous blog post was published a month ago), the YaST Team is back with some news about the latest development sprint and some Hack Week experiments. Those news include:

• Enabling YaST on the Windows Subsystem for Linux
• Usability improvements for the Online Search, the Partitioner and the Kdump module
• Better control of overridden sysctl configuration values
• Improvements in the default selections of the upcoming SLE 15 SP2 installer
• New features for zSeries mainframes like Secure Boot and I/O devices auto-configuration
• And, as a bonus, a couple of Hack Week projects related to YaST, Ruby and Crystal

So, as you can see, we have a little bit of everything in the menu, from WSL to mainframes, from new features to small usability improvements, from installation to system fine-tuning… So let’s dive into the details!

Improved compatibility with WSL

Have you ever heard about WSL, the Windows Subsystem for Linux? To be honest, before this sprint we haven’t payed much attention to it either. But as both openSUSE Leap and SUSE Linux Enterprise (SLE) are available to Windows users via WSL images and the 15.2 releases of both distributions are approaching, we decided it was time to dive into WSL to research how it works and how can YaST be useful there.

Setting up an (open)SUSE test system inside a WSL environment was a piece of cake thanks to the excellent documentation at the openSUSE Wiki.

Many components of YaST are useless in WSL because not everything can actually be configured from the Linux system itself and because systemd is not available (we are talking exclusively about WSL1 here). But YaST is still very useful for the initial setup of the system when running the (open)SUSE image for the first time. It can be used to setup the first user, to confirm the license and, in the SLE case, also to register the system. The YaST modules for software management can also be very handy to customize the image at any point after that initial setup.

So far, we have done three changes to improve the experience of executing YaST within WSL.

• We increased the speed of the initial boot by removing calls to systemd when it is not available.
• We fixed the registration process for YaST Firstboot.
• We implemented a feature to explicitly mark YaST modules that work in WSL and show only those modules in the YaST control center.

We also documented all our findings about WSL in this document.

As always, we are hungry for feedback. Please reach out to us and tell us what’s your experience using YaST inside WSL and which modules do you miss the most.

Improving the UX of the Online Search

As we announced one month ago, YaST will offer a mechanism to search for packages through all SUSE Linux Enterprise modules, even if they are not registered. This feature, known as package online search, was already available using zypper’s search-packages command or through the SCC web interface.

After gathering some feedback during the sprint review meeting, we decided to invest some time improving the overall UX experience. Perhaps the most relevant change is the new summary screen, which shows the list of modules to activate and packages to install.
