SAM reporting 0 repositories when YUM repositories are being used created by ZCM

sam reports the following: *** Found package repositories: 0

To update a server, yum repositories are being used that are created by ZCM.

The problem has 2 parts:

• The yum repositories are not signed. Please see this cool solution how this can be achieved.
• Run sam with the option --no-strict-repo-description
  

When creating a YUM repository with ZCM, the repomd.xml is not digitally signed and also ZCM is not providing label, distribution and version. This prevents sam, when started with no options, to display the repository information
