    Testing of OSCI packages on a stable environment

    1. Enables the 'custom_repo' decorator which add new rpm/deb
    packages to FUEL master node from custom repository before
    OS cluster is created. Can be used with any system test.

    2. In case of deployment error, checks the puppet logs
    in /var/log/docker-logs/remote/node-*/ for unmet dependences
    of packages which are failed to install during deployment.

    Use the following environment variables:
    * required:
      CUSTOM_PKGS_MIRROR=<URL to repository>

I suggest contacting the author of the commit, or check logs from the environment. MOS Linux has nothing to do here.
