IMPORTANT: Do not select Always Show Preboot Menu if you have AutoYaST or kickstart
bundles assigned to any devices, because the Preboot Services Menu interrupts the PXE boot
process, keeping the AutoYaST or kickstart bundles from being deployed on the device. The Preboot
Services Menu only has options for doing imaging work, not for installing operating systems.
Therefore, select either Never Show Preboot Menu or Show Preboot Menu if CTRL+ALT is Pressed
for your Preboot Services Menu option, which allows PXE-enabled Linux devices to automatically
implement the AutoYaST or kickstart bundles.
For the procedures in configuring whether to display the menu, see Section 29.4.1, “Configuring
Preboot Services Menu Options,” on page 380 .
28.3.3 Image Storage Security
You can determine the degree of security you want by restricting where to save image files on your
imaging server. The following options in the ZENworks Control Center provide this storage
security:
Š Allow Preboot Services to overwrite existing files when uploading: Select this option only
if you want existing image files to be overwritten during imaging.
Š
Only allow uploads to the following directories: This option allows you to determine where
images can be restored on the imaging server. You specify a full path to the directory in the Add
field, then click Add to enter it into the list box. These are the directories where images are
allowed to be saved on the imaging server. These are the locations that can be selected when
configuring where to store image files.
For the procedures in configuring imaging storage, see Section 29.4.2, “Configuring Image Storage
Security,” on page 381 .
28.3.4 Non-registered Device Settings
Devices that are new to the ZENworks Management Zone and have received their first image need
certain IP configuration information to successfully access the network and network services. You
can use Preboot Services to automatically name your non-registered devices using such criteria as
prefixes, BIOS information (like asset tags or serial numbers), DNS suffixes, and you can set up
DHCP or IP addresses.
For example, the device needs a unique IP address and the address of at least one DNS name server.
In many networks, this information is distributed through the DHCP services, but it can also be
configured through the default Preboot Services configuration settings in the ZENworks Control
Center.
After a device has registered with ZENworks, its configuration is set and the non-registered device
settings in the ZENworks Management Zone no longer apply to it, because the ZENworks Linux
Management server now knows its identity. After the device is imaged, it can become a member of
the zone or continue to be a non-registered device, depending on whether the image applied to the
device contains the ZENworks Linux Management Imaging Agent (
novell-zislnx ).
The settings that can be adjusted for a ZENworks Management Zone are:
Š NDS suffix: Provides a suffix for all of your devices’ names. For example, provo.novell.com.
