You can launch the Symantec Installation Manager from a command line and pass it an XML based config file. This allows you to do a silent install of any suite or solution. All you have to do is identify the product or suite you want to install. The Product Guid can be pulled out of the symantec.pl.xml file. You should load this into some type of tool like Notepad++ and pay attention to all the tags. There are a number of items in here that give you complete flexibility. This example is installing CMS 7.1 and AMS 7.1 to the D: drive and enabling SSL for example.
