Configuration Sets in Standard 7 (Standard 7 SP1)
A configuration set is a subset of a distribution share that you create by using Image Configuration Editor A configuration set exports binaries referenced in the unattended answer file and puts them together into a self-contained file set that is available from the Unattend.xml file. You can create a configuration set after an unattended answer file has been validated and saved. Configuration sets are useful when a network share is not available because you can store configuration sets on removable media to use in the field.
The benefits of using configuration sets for unattended installations are as follows:
A configuration set is a smaller and more portable version of a distribution share, which can be several gigabytes. You can use configuration sets to install Standard 7 operating systems in the field.
Configuration sets are completely self-contained and have no references outside the file set.
You can duplicate a configuration set and then edit it for each computer model that you manufacture and release.
Note: If you use a configuration set during Image Builder, all the contents at the root of the media where the answer file exists are copied to the Standard 7 installation. If many folders and files exist at this level, installation might slow down, and, in some cases, you might run out of disk space.
