Comment # 2 on bug 1183611 from Ancor Gonzalez Sosa

What I can see in the screenshot is that the YaST Patterns are not marked for
installation. That doesn't prevent the installation of all packages included in
the pattern.

YaST may still be installed due to dependencies with other selected packages or
patterns.

Please, attach YaST logs to check whether we can see what dragged YaST in

Please, also make sure you understand the concept of zypper patterns.
