In this step of the Linux RPM media wizard you define which user variables should be overridden for this media file.

User variables are defined on the User variables tab of the General settings step, but can be overridden on a per-media file basis. For example, this is useful to internationalize the application name and other text displayed in the installer or to change the native library directories in a launcher definition. The variable table shows 4 columns: Override marker If you have overriden a variable by editing the value column, the first column will display a  marker to indicate that that variable has been overridden. In that case, the reset button column will display a button to restore the original value. Variable name Shows the name of the variable. Variable value Shows the value of the variable. This column is editable. To override the variable, double-click on the desired cell in this column and edit the value. The override marker column and the reset button column will then show that the variable has been overridden. Reset button If a variable has been overriden, this column shows a [Reset] button that allows you to restore the original value as defined on the User variables tab of the General settings step

Overriding variables on a per-media file basis is also possible from the command line and from the ant task.
