This section contains the following information:
Each patch has a category and a status associated with it. The categories state whether the patch is a security patch, a recommended patch, or an optional patch. The zypper pch command shows whether the patch is needed or not needed and whether it has been applied. When you are using the Novell Updater, only the patches that are needed and have not been applied display in the list of patches.
Therefore, you can just apply all the security patches and wait to apply other patches that might change how a feature or product works.
