Solaris 10 Installation Guide: Solaris Flash Archives (Creation and Installation)

Planning to Create the Solaris Flash Differential Archive for an Update

If you have a clone system that is already installed with an archive and want to update it, you can create a differential archive that contains only the differences between two images, the unchanged master image and an updated master image. The differences between these two images is the differential archive.

After you update a clone system with a differential archive, only the files that are in the differential archive are changed on the clone system. Scripts can be used to customize the archive before or after installation, which is especially helpful for reconfiguration.

You can install a Solaris Flash differential archive with the custom JumpStart installation method. Or, you can use Solaris Live Upgrade to install a differential archive on an inactive boot environment.

An unchanged master image should be saved after the initial installation so this image can be accessed by any of the following methods.
