Where you are using a ZENworks partition, you can boot to the manual or maintenance mode,
mount the ZENworks partition, then copy the modified
settings.txt
and the files in
initrd
or
root
to the mounted ZENworks partition.
Š
Another easy method is to edit the
.cfg
files located in
/srv/tftp
on the ZENworks Imaging
Server for PXE booting. This method is only available for Linux Imaging Servers, because the
configuration files are provided by Novell’s version of PXE.
Š
You can modify files in the
initrd
or
root
file systems, but you need a Linux environment for
performing the modification process. Files required during the initial setup (during linuxrc
processing time), such as LAN drivers, must be placed in the
initrd
file system. Other files
that are not needed until the
zenworks.s
script file takes control can be placed in the
root
file
system (for example, an imaging script), or you can use the
driverupdate
file.
This method is discussed in this section.

F.4.1 Adding Files to an Imaging Boot CD
If you have files to add to an imaging boot CD so they can be available for use when you get to the
actual imaging process (such as scripts, but normally not driver modules), you can copy the files to
the
/addfiles
directory on the imaging CD. This is an easy way to insert your script or other files
into the distribution without modifying the initrd or root file systems . However, these files are not
available during the boot and module loading phases.
The imaging boot CD has a directory named
/addfiles
where you can add files. They should be
placed below this directory in their proper directory names. They are then available in this directory
structure during the imaging process.
An example of how you can add files:
1 If you want to execute your own script instead of the normal imaging process, create a script
file named
myscript.s
and place it on the boot CD. For example,
/addfiles/bin/
myscript.s
.
IMPORTANT: The script file must have proper LF line terminators that Linux requires, not
the DOS CR and LF end-of-line characters. In other words, you cannot use
Notepad.exe
to
create the script; you must use a text editor compatible with Linux, such as TextPad.
2 To place the following line in the
settings.txt
file, enter:
export IMGCMD="/bin/myscript.s"
When imaging is run, it runs
/bin/myscript.s
instead of using the normal
img -auto
command.
F.4.2 Adding Files to the Initrd or Root File Systems
This is the preferred method for updating imaging resource files, and must be performed in a Linux
environment.
