Introduction

After the system has booted into an automatic installation and the control file has been retrieved, YaST configures the system according to the information provided in the control file. All configuration settings are summarized in a window that is shown by default and should be deactivated if a fully automatic installation is needed.

By the time YaST displays the summary of the configuration, YaST has only probed hardware and prepared the system for auto-installation. Nothing has been changed in the system yet. In case of any error, you can still abort the process.

A system should be automatically installable without the need to have any graphic adaptor or monitor. Having a monitor attached to the client machine is nevertheless recommended so you can supervise the process and to get feedback in case of errors. Choose between the graphical (Qt or GTK) and the text-based Ncurses interfaces. For headless clients, system messages can be monitored using the serial console.

X11 Interface (graphical)

This is the default interface while auto-installing. No special variables are required to activate it.

Serial console

Start installing a system using the serial console by adding the keyword "console" (i.e. console=ttyS0) to the command line of the kernel. This starts linuxrc in console mode and later YaST in serial console mode.

Text-based YaST Installation

This option can also be activated on the command line. This will start YaST2 in Ncurses mode. To start YaST in text mode, add textmode=1 on the command line.

Starting YaST in text mode is recommended when installing a client with less than 64 MB or when X11 is not being configured at all, especially on headless machines.
