A standard Linux installation asks many questions about what to install, what hardware to configure, how to configure the network interface, etc. Answering these questions once is informative and maybe even fun. But imagine a system engineer who needs to set up a new Linux network with many machines. Now, the same issues need to be addressed and the same questions answered repeatedly. This makes the task very inefficient, not to mention a source of irritation and boredom. Hence, a need arises to automate this parameter and option selection.
The thought of simply copying the hard disks naturally crosses one's mind. This can be done quickly, and all the necessary functions and software will be copied without option selection. However, the fact is that simple copying of hard disks causes the individual computers to become too similar. This, in turn, creates an altogether new mission of having to reconfigure the individual settings on each PC. For example, IP addresses for each machine will need to be reset. If this is not done properly, strange and inexplicable behavior results.
A regular installation of SUSE Linux Enterprise Server is semi-automated by default. The user is requested to select the necessary information at the beginning of the installation (usually language only), YaST then generates a proposal for the underlying system depending on different factors and system parameters. Usually—and especially for new systems—such a proposal can be used to install the system and provides a usable installation. The steps following the proposal are fully automated.
AutoYaST can be used where no user intervention is required or where customization is required. Using an AutoYaST control file, YaST prepares the system for a custom installation and avoids any interaction with the user, unless specified in the file controlling the installation.
AutoYaST is not an automated GUI system. This means that usually many screens will be skipped—you will never see the language selection interface, for example. AutoYaST will simply pass the language parameter to the sub-system without displaying any language related interface.
