new mock root/configuration names

Hi, mock --root have new names for RPMFusion , while still be backward compatible, mock-core-configs package as you may notice due Centos Stream and his replacements like Alma and Rocky adopt new root names . Also to work with copr is necessary or patch the copr or adapt names to what copr expect. where %{repo name} can be fedora+rpmfusion_free or fedora+rpmfusion_nonfree or epel+rpmfusion_free or epel+rpmfusion_nonfree or epel-next+rpmfusion_free or epel- next+rpmfusion_nonfree and the complete root name is %{repo name}-%{version}-%{arch} So fedora+rpmfusion_free-36-x86_64 is the new name for "old" fedora-36- x86_64-rpmfusion_free . So since mock-rpmfusion-37.1-1 we should use mock -r fedora+rpmfusion_free-36-x86_64 I felt, I should give some explanations about the new version of mock- rpmfusion ( https://github.com/rpmfusion-infra/mock-rpmfusion/commits ). Is also about "use mock templating as mock use" ( https://github.com/rpmfusion-infra/mock-rpmfusion/commits/35.2 ) And start the support for EPEL-next , this started almost one year ago with https://github.com/rpmfusion-infra/mock-rpmfusion/pull/20 (I will review typos later) Feedback is welcome :) Have a nice hacking -- Sérgio M.
