The openSUSE project has released Leap 16, its first major release since openSUSE Leap 15 in May 2018. This release brings some changes to the core of the distribution aside from the usual software upgrades; YaST has been retired, SELinux has replaced AppArmor as the default mandatory access control (MAC) system, and more.
So far, there’s no replacement for many parts of YaST that I use frequently, so I’m holding onto them until they stop working. Supposedly, more Cockpit addons are planned or in the works. I do hope that it eventually can do all the things YaST used to be able to do. It was a great tool.
