## Solaris Boot Image

A Solaris boot image is a set of files that is used with a matching archive to install and update managed hosts. The Solaris version of the boot image and the archive must be identical for installation tasks and update tasks to succeed. The Solaris boot image is used as input for an installation or an update action and is associated with an archive. A Solaris boot image is also known as a miniroot.

For installations, the boot image boots the Solaris operating environment on the managed host and runs the Solaris Flash installation program. For updates, the boot image runs the Solaris Flash installation program.

A single boot image can support several archives. The Solaris version of the boot image and the archive must match. For example, a Solaris 8 2/02 boot image must be used to deploy archives based on the Solaris 8 2/02 release.

The Solaris boot image file name must use the `.miniroot` suffix.

In addition to the general file properties, a Solaris boot image is associated with the following property:

`OSVersion`

  User-supplied string that describes the version of the Solaris operating system associated with the boot image.

To deploy software to a managed host, see How to Perform an Initial Installation (Web Browser) and How to Reinstall, Update, Fall Back, and Reboot Managed Hosts (Web Browser), or How to Perform an Initial Installation (Command Line), How to Reinstall Managed Hosts (Command Line), and How to Update Managed Hosts (Command Line).
