Even though only CD-based images can have multiple answer files associated with them, both CD-based and RIPrep images use answer files during the installation process, and the handling of an answer file for a specific installation is handled the same for both image types.
Using answer files with RIS also allows OSChooser (OSC) variables to be embedded within them. (For more information about OSC variables, see "OSCML and Client Installation Wizard Variables" in this book.) OSC variables are replaced with user, server, installation, or client-specific data, and then a completely configured answer file specific to the individual installation attempt is written to a temporary location (the \Reminst\Tmp folder) on the RIS server. The file name of the temporary answer file is the raw GUID in hexadecimal with .sif appended. For example, if the client has a GUID of {78563412-3412-3412-1234-123456789AB}, the raw format is 12345678123412341234123456789AB and a generated answer file name is "12345678123412341234123456789AB.sif." The client is then instructed to use this answer file to control the installation of the image. At the end of text-mode setup, setup deletes the temporary answer file.
Note
Because the location where the temporary answer file is created is open for anyone to read, embedding passwords (such as the administrator's password) into an answer file is a security risk.
