First, let me mention a design change: In Deployment 4, there are no longer any "builds" in the Deployment Workbench. Instead of creating a build, you will create a task sequence. This is more in line with the System Center Configuration Manager way of doing things. Behind the scenes, much of the same configuration exists; it's just presented differently.
Next, we now support multiple task sequence templates. Right now, we have provided three templates for Lite Touch and SMS 2003 deployments:
There are also three templates for ConfigMgr 2007, equivalent to the ones above:
If you wanted, you could also create your own templates. Just drop them into the \Program Files\Deployment 4\Templates directory (for Lite Touch or SMS 2003) or the \Program Files\Deployment 4\SCCM directory (for ConfigMgr 2007) and we'll automatically find them. (Be sure to change the description in the file so you can tell which one is which.)
