Novell ZENWORKS LINUX MANAGEMENT 7.3 IR2 - ADMINISTRATION GUIDE 02-12-2010 Administration Manual page 222

If you want a bundle to be platform-specific, you must use a script and have the script
verify the target platform before deploying and installing the bundle.
Install type: Use the Install type drop-down list to choose from the following installation
options:
Freshen (upgrade only if installed): Use this option to transact a package only if a
previous version of the package is already installed on the device. You can use the Freshen
option in conjunction with the Auto-detect, Update, or Install options.
6b (Optional) Click Add > Import from repository to open the Package Import dialog box,
then select the packages to import. You can use the Search options on the right side of the
Package Import dialog box to locate packages.

Auto-detect: Automatically detects whether the bundle is already installed on
assigned devices and either installs the bundle or updates an existing bundle, if
necessary. Basically, the Auto-detect option determines whether the Update or the
Install option functionality (explained below) is best, and then performs that
operation. Any kernel packages are installed using the Install option functionality;
other packages are installed using the Update option functionality. This is the default
option and should be used in most situations.
Update: Updates the packages on assigned devices if the packages in the bundle are
newer than what is installed on the devices. If the packages are not installed on the
assigned devices, ZENworks Linux Management installs them. With the Update
option, you don't need to worry whether a package is already installed because the
package is either updated (if needed) or installed on the device. Parallel installation
of a package is not possible with the Update option.
Install: Installs the bundle on all assigned devices. If previous versions of the
packages exist on the devices, ZENworks Linux Management does not update the
existing packages. As a result, packages can be installed multiple times (parallel
installations), which might cause overlap issues. This option is rarely used; you
should use the default option, Auto-detect, under most circumstances. You should use
this option almost exclusively to install kernel packages.
