YaST
YaST - Yet Another Setup Tool. YaST is a operating-system setup and configuration tool which is featured in the SuSE Linux distribution. Furthermore, it is part of United Linux.
Although its license permits modification, creating the appearance of a free software license, redistribution is only allowed free of charge, only on ftp-servers and “mailboxes” (BBS systems), and only together with SuSE Linux. Thus, YaST is generally not considered free software and is not found in any other Linux distribution.
