For Phase 0, customization of the installed virtual machine is entirely dependant on the capabilities to customize an AI client installation (since we're going to use the AI client technology to perform the actual installation). This means, that if you want to customize the install you'll need to create an IPS package which contains your customizations and you'll have to propogate that to the IPS repository you use for the AI client installation. In later phases, it's possible that we'll provide for other ways of customizing the installed image. For instance, if the AI image were to carry a payload (TM via cpio instead of the current IPS) then you could create a finalizer script that customizes the image during construction and then gets propogated to the installation. -- Glenn
