YaST and SUSE Linux Enterprise in general can be configured to use different languages according to your needs. The language selected here is also used for the keyboard layout. In addition, YaST uses the language setting to guess a time zone for the system clock. These settings can be modified later along with the selection of secondary languages to install on your system.
You can change the language later during installation as described in Section 3.9, “Installation Settings”. For information about language settings in the installed system, see Section 8.1, “YaST Language”.
