Preboot Services allows you to automatically or manually do any of the following to a Linux device when it boots:
Run AutoYaST and kickstart installations
Run ZENworks scripts on the device
Make an image of the device’s hard drives
Restore an image to the device
Apply an existing image to multiple devices
Configure Dell devices
To accomplish these tasks automatically using the ZENworks Control Center, you simply need to have PXE (Preboot Execution Environment) enabled on your devices, and have preboot bundles configured and assigned to the devices. Then, the devices can automatically execute these bundles when they boot.
You can also execute some Preboot tasks on devices using CDs, DVDs, or a ZENworks partition, rather than using PXE.
