Some noted bugs with YaST in openSuse 11.2:

Whenever you add/remove packages via YaST control center, after the package is installed or removed YaST reruns suseConfig for several services (that are not part of the package installation/removal you just made) and then terminates taking you back to. It would be better if the application would take you back to the software mgr interface and then run suseConfig only for whatever services were installed/removed rather than everything.

If removing a package and selecting Selected by the User for the action, YaST installs recommended replacement packages anyway.

The help system associated with the various configuration tools within YaST control center needs improvement and more detailed information to be very useful.
