YaST (Yet another Setup Tool[1]), is an RPM-based operating system setup and configuration tool that is featured in the openSUSE Linux distribution, as well as Novell's derived commercial distributions. It features tools that can configure many aspects of the system. It is also part of the defunct United Linux. The first SuSE distribution that included YaST was released in May, 1996.

YaST is free software that Novell has made available under the GPL.[2]

YaST2 is a tool for administering and maintaining a SUSE Linux installation. It allows administrators to install software, configure hardware, set up networks and servers, and more.

A feature of YaST is that it contains both GUI and ncurses front ends. This is especially useful for non-GUI installations, for system administration over slow Internet connections, and for when one is unable to boot into a graphical X server but still requires an advanced user interface to the package manager (for example, a novice user trying to downgrade an Xorg package to fix a graphical installation).

YaST's display configuration module is called SaX2 (which stands for SUSE Automated X configuration, version 2).

openSUSE 10.3 features a redesigned YaST for GNOME users. Among the new modules are the "Community Repositories" which is a tool to easily add much used repositories and the KIWI imaging tool which easily lets you roll out your own custom SUSE images.

YaST offers package management functionality through the ZYpp project.[3] The first ZYpp enabled package management YaST applications had performance problems and long start up times, but was improved in the 10.2 and 10.3 releases. Starting with openSUSE 11.0 alpha 3, ZYpp was integrated with the SAT solver project, making YaST and zypper faster than other rpm based package managers.[4]

AutoYaST is a system for installing one or more openSUSE systems automatically without user intervention. AutoYaST installations are performed using a control file with installation and configuration data. The profile of each current system is stored in /root/autoyast.xml.[5]
