8 Select the partitions that you want to include in the image.
9 Select a compression option:
None: No compression is used.
Speed: Takes the least amount of time to compress but creates the largest compressed image
file. This option is used by default when an image is created.
Balanced: Represents a compromise between compression time and image file size.
Size: Creates the smallest image file but takes longer to compress.
10 Click Next.
11 (Optional) Fill in the fields:
Author: The name of the person creating this image.
Computer: The name of the computer being imaged.
Image description: A description of the image.
Comments: Any additional comments about the image.
12 Click Next.
Depending on the amount of data on the hard disk, the image might take several minutes to
create. If the screen goes blank, just press any key. (Linux enters a screen-saving mode after a
few minutes.)
13 After the image is created, exit from the ZENworks Imaging Engine menu, remove any CD or
DVD from the drive, then reboot the device.
14 (Optional) Verify that the image file was created on your imaging server. You might also want
to check its size.
Using Image Explorer to Customize an Image
After you have created a base or add-on image as explained in the previous sections, you can
customize it with the Image Explorer utility. Specifically, you can:
Compress the image: You can compress an image (including images created by previous
versions of ZENworks Linux Management) to 40-60% of the original file size, if you have not
done so already during the imaging process. There are three compression options. Optimize for
speed takes the least amount of time but creates the largest compressed image file. Optimize for
space creates the smallest image file but might take a significant amount of time. Balanced is a
compromise between compression time and image file size. This option is used by default
when an image is created.
ZENworks Linux Management provides the following compression methods:
Compress: Use this option to compress an image file that you currently have open in
Image Explorer. For more information, see
QuickCompress: Use this option to compress an image file without waiting for the file to
fully load into Image Explorer. For more information, see
without Waiting for the File to Fully Load into Image Explorer" on page
Split the image: You can specify a device image file that you want to split into separate files so
that the entire image can be spanned across several CDs or DVDs. Splitting a device image is
helpful for putting down or restoring images in a disconnected environment. For more
information, see
