Approach

1. Create a request script script to ask the installer how the set should be installed.

2. Should default installation be performed on this set?

   When the answer is yes, if any of the set's member packages require interaction and if default responses for that interaction have been provided, install the set using the default responses.

   When the answer is no, for each package in the set, prompt as to whether this package should be installed.

   When the answer is yes, if it is interactive (the package has a request script), should default installation of the package be performed?

   If yes, use the default response file.

   If no, execute the package's request script to obtain the responses.

3. When the request script has completed, the PKGLIST variable should contain the list of selected set member packages that will be installed on the system. At this time:

   • pkgadd(ADM) runs the SIP's preinstall script which places the selected set member packages for installation ($PKGLIST) into the setlist file referenced using the $SETLIST variable.

   • pkgadd then reads the setlist file and inserts the packages listed there into the list of packages to be installed on the system.

   • As each of these packages is processed, if the package is interactive, pkgadd uses the response file created earlier so that no prompting for user input occurs except during SIP processing.
