Resize a partition in an image: For base images, you can edit the value in the Original size
text box to allow you to change how big the ZENworks Imaging Engine makes the partition
when the image is restored. For more information, see
Section D.1.16, “Resizing a Partition in
an Image,” on page 612 .
Š
Purge deleted files: Excluded or hidden files and folders can be completely removed from an
open image. This saves space in the image if you no longer want to include the files. For more
information, see
Section D.1.5, “Excluding a File or Folder from a File Set in the Open Image,”
on page 609 .
Š
Exclude individual files and folders from the image: In doing this, you create subsets of the
image by specifying which of ten possible file sets to exclude a given file or folder from. This
exists merely as internal attributes of the same image archive. For more information, see
Section D.1.7, “Purging Files and Folders Marked for Deletion from the Open Image,” on
page 609
.
IMPORTANT: Do not exclude BPB files from a base image or the device won’t be able to
boot the new operating system after receiving the image.
Š
Add files and folders to the image: By default, any file or folder you add is included in all file
sets. To change this, you must explicitly exclude the file or folder from one or more file sets.
For more information, see
Section D.1.3, “Adding a File or Folder to an Open Image,” on
page 608 .
For information on starting Image Explorer, see Section D.1, “Image Explorer (imgexp.exe),” on
page 607 .
Creating an Add-On Image
An add-on image is an archived collection of files to be applied to an existing installation on a target
device. This is sometimes referred to as an application overlay. The existing partitions and files on
the target device are left intact, except for any files that the add-on image might update.
An add-on image typically corresponds to an application or utility, or simply to a set of data files or
configuration settings.
To create an add-on image:
1
Run the Image Explorer utility, which is located on the Linux imaging server at:
/opt/novell/zenworks/zdm/winutils/ImgExp.exe
2 Drag files and folders from an existing device into a new image archive.
For more information, see
Section D.1, “Image Explorer (imgexp.exe),” on page 607 .
3 Save this image with the
.zmg
extension (case-sensitive) in the same directory on the imaging
server where you store base images.
Generally, an add-on image created in this manner doesn’t require any post-processing on the
target device. It is simply a set of files that are copied to the appropriate locations on the hard
disk, much like what happens when you unzip an archive. For more information, see
“Using
Image Explorer to Customize an Image” on page 418 .
This add-on image can be used in Step 8 on page 412 under “Configuring the ZENworks Image
Bundle for Automatic Imaging” on page 410 .
