2.3 Software

2.3.1 Change Installation Source

The installation source is the medium containing the software to install.

YaST can administer a number of different installation sources. It enables

their selection for installation or update purposes. For example, add the

SUSE Software Development Kit CDs as an installation source.

When this module starts, it displays a list of all previously registered

sources. Following a normal installation from CD, only the installation CD

is listed. Click ‘Add’ to include additional sources in this list. You can add

removable media, such as CDs, and network servers, such as NFS and FTP.

Even directories on the local hard disk can be selected as the installation

medium. See the detailed YaST help text.

During the installation or update, YaST can take multiple installation

sources into consideration. All registered sources have an activation sta-

tus in the ﬁrst column of the list. Click ‘Activate or Deactivate’ to activate

or deactivate individual installation sources. During the installation of

software packages or updates, YaST selects the suitable installation source

from the range of activated installation sources. When you exit the module

with ‘Close’, the current settings are saved and applied to the conﬁguration

modules ‘Install and Remove Software’ and ‘System Update’.

2.3.2 YaST Online Update

The YaST Online Update (YOU) enables the installation of important up-

dates and improvements. The current patches for your SUSE product

are available from the SUSE Maintenance Web service. With ‘Installation

Source’ select one of the various servers. When you select a server, its URL

is copied to the input ﬁeld, where it can be edited. Specify local URLs in the

form file:/my/path or /my/path. Expand the existing list with addi-

tional servers using ‘New Server’. Click ‘Edit Server’ to modify the settings

of the currently selected server.
