Yast introduction
Yast stand for Yet Another Setup Tool
Yast work in SLES installation and after installing
AutoYaST [like control panel in windows ] to control operating system SLES
AutoYaST installations are performed using an AutoYaST control file (also called “profile”) with installation and configuration data.
That control file can be created using the configuration interface of AutoYaST and can be provided to YaST during installation in different ways.
The YaST user interface can appear in two modes:
- ncurses (Yast Text mode)
- Qt (Yast2 Fully graphical mode)
Yast and SuSEConfig
SuSEconfig acts as a backend for YaST2 and activates the configuration changes that made by yast2
SuSEconfig is automatically executed by Yast whenever you install, update or remove any package from the system. because newly installed packages may have included changes to the configuration options in /etc/sysconfig/
SuSEconfig configures the system according to the variables that are set in the various “/etc/sysconfig/” files
