Use the following command to test:

    sudo yum install Parent --assumeno --disablerepo=* --repofrompath=example6,http://people.redhat.com/kwalker/weakdeps/example6/
    sudo yum install Parent --assumeno --setopt=install_weak_deps=False --disablerepo=* --repofrompath=example6,http://people.redhat.com/kwalker/weakdeps/example6/

Output:

    # sudo yum install Parent --assumeno --disablerepo=* --repofrompath=example6,http://people.redhat.com/kwalker/weakdeps/example6/
