2.0 AutoYaST Work Flow Overview
The automated installation of any SLES based system consists of three distinct steps:
-
The installation system is booted and network connectivity is established.
-
In Stage 1 the AutoYaST control file is located and retrieved. Pre-scripts, if any, are executed, the system is installed and rebooted.
-
In Stage 2 the system is configured and post-scripts and init-scripts, if any, are executed.
Figure 2-1 AutoYaST Process Overview
This is illustrated in the figure above. Note that even so a manual installation of SLES12 and later is performed in one stage an AutoYaST installation of these releases is still executed in two stages.
