Linuxrc attempts to locate and load the settings.txt file, either on the root of the imaging CD,
or on the ZENworks imaging server in the /srv/tftp/boot directory. From settings.txt,
linuxrc reads and processes any parameters that pertain to itself, then copies settings.txt to the
root ( / ) of the file system.
Linuxrc then also attempts to locate and load a file named driverupdate. It is usually located in
the same directory as root. This file is used to update drivers and other files in the imaging
distribution.
The driverupdate file is based on standard SUSE technology during a PXE boot. Because the
network must be operating normally in order to obtain driverupdate, this file cannot update
drivers for the active network device. However, other files and drivers can be updated by using the
driverupdate file. For more information, see
Method," on page 640.

F.2.2 zenworks.s

A normal SUSE installation for SUSE Linux or SLES boots to a small distribution to perform a
YaST installation. ZENworks Imaging boots with the same installation system, but instead of
starting a YaST installation, it starts the ZENworks Imaging process. Control is turned over to the
ZENworks script /bin/zenworks.s, which is the main script file for ZENworks imaging
processing. The script performs a certain number of setup tasks, then gives control to the appropriate
script for the selected imaging process. For more information on the imaging process, see
Chapter 28, "Understanding Preboot Services in ZENworks Linux Management," on page
One of the setup tasks is to apply any update files. When booting from a CD, zenworks.s copies
the /addfiles directory structure to the Linux file system. For more information, see

F.3 Understanding ZENworks Partitions and
Command Line Parameters
The following sections provide an understanding of the ZENworks partition and imaging commands
that are used when updating Linux drivers:

Section F.3.2, "Command Line Parameters and Variables," on page 636

F.3.1 The ZENworks Partition

The ZENworks partition is used to store the files required to load Linux into RAM, making the
result similar to using a CD or PXE boot method. The ZENworks partition has a similar boot media
layout as an imaging CD. It has a minimum size of 150 MB.
The files stored on the ZENworks partition are /boot/loader/linux, /boot/loader/
initrd, and /boot/root, which are the same directories as on the imaging CD. In ZENworks
7, the boot loader continues to be lilo, which loads Linux as described under
"Understanding Device Boot Processes in a ZENworks Imaging Environment," on page
driverupdate and settings.txt files are searched for and loaded from the ZENworks
partition.
