Novell ZENworks 7 Linux Management - ZLM7
Novell SUSE Linux Enterprise Desktop 10
Novell SUSE Linux Enterprise Server 10
SLE 10 managed device subscribed to ZLM 7 or ZLM 7 DE server. The server has mirrored updates from for SLE 10 devices. However, the server does not contain the base packages for SLE 10.


Doing a rug up on the managed device causes dependency resolution to report that several packages need to be removed due to failing dependencies, where they should not. One specific example is where the package aaa_base is reported to be removed because there are no providers for the file /usr/bin/cmp, even though /usr/bin/cmp is'implicitly' provided by an updated package, diffutils.


ZLM does not support a scenario where it is used purely for upgrades. Therefore, one must upload the entire packages that are part of the SLE 10 distribution into ZLM along with the upgrades. This would cause ZLM to calculate the dependencies correctly and make them available to the client. See KB 3339684 for detailed instructions on how to do that.

Additional Information

When a package is added to the ZLM server, say via mirroring, it creates a metadata file (bundle.xml) which the client will download. This metadata file contains information such as the capabilities that the package provides. In creating this information, ZLM merges the explicit and implicit capabilities that are provided by the package. Implicit capabilities include the file list defined in a package, such as /usr/bin/cmp provided by diffutils. In order to reduce the amount of information to store on the server and also reduce the amount of metadata information that would require to be downloaded to the client, ZLM stores only those implicit capabilities that are required by other packages on the server. Traditionally, this design met the needs of most customer environments, as the ZLM server had both the base packages and updates.
