centos-release-storage-common is a package shared between the different
projects of the CentOS Storage SIG. This package contains the public GPG key
that is used for verification of the released RPMs.

 - core7-extras-common-el7.centos (tag: core7-extras-common-candidate)
 - core6-extras-common-el6.centos (tag: core6-extras-common-candidate)

        --define "_sourcedir $PWD/SOURCES" --define "_srcrpmdir $PWD" \
        --define "dist .el8s.centos" \
        SPECS/centos-release-storage-common.spec
