Yet another Setup Tool (YaST)

YaST (yet another setup tool) is the configuration tool for the openSUSE Linux operating system (OS). 

YaST is a Ret Hat package manager-based OS setup. Administrators can install software, configure hardware and set up networks and servers. YaST is widely accepted for its easy-to-use graphical interface and the ability to quickly customize a system during and after installation. It contains tools for configuration and an ncurses front end for low-bandwidth text-based control.  On SUSE Linux Enterprise Server (SLES), YaST learns the current version of the configuration files and displays manually adjusted modifications, removing the risk of accidental damage when building complex configurations. YaST is also featured in Novell's derived commercial distributions.

AutoYaST installs multiple openSUSE systems automatically, without human intervention. Its installations are executed through a control file with installation and configuration data. YaST can also work through a Web interface called WebYaST.
