Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 04-08-2006 Installation Manual page 145

When the package manager starts, it examines the system and displays installed pack-
ages. When you select to install and remove packages, the package manager automati-
cally checks the dependencies and selects any other required packages (resolution of
dependencies). If you select or deselect conflicting packages, the package manager in-
dicates this and submits suggestions for solving the problem (resolution of conflicts).
Check Dependencies and Autocheck are located under the information window. If you
click Check Dependencies, the package manager checks if the current package selection
results in any unresolved package dependencies or conflicts. In the event of unresolved
dependencies, the required additional packages are selected automatically. For package
conflicts, the package manager opens a dialog that shows the conflict and offers various
options for solving the problem.
If you activate Autocheck, any change of a package status triggers an automatic check.
This is a useful feature, because the consistency of the package selection is monitored
permanently. However, this process consumes resources and can slow down the package
manager. For this reason, the autocheck is not activated by default. In either case, a
consistency check is performed when you confirm your selection with Accept.
For example, sendmail and postfix may not be installed concurrently.
"Conflict Management of the Package Manager"
prompting you to make a decision. postfix is already installed. Accordingly, you
can refrain from installing sendmail, remove postfix, or take the risk and ignore
the conflict.
WARNING: Handling Package Conflicts
Unless you are very experienced, follow the suggestions of YaST when handling
package conflicts, because otherwise the stability and functionality of your
system could be endangered by the existing conflict.
