Somebody would have to test the actual compatibility, because:
# fedora has its own implementation
rm %{buildroot}%{_bindir}/update-alternatives
rm %{buildroot}%{_mandir}/man8/update-alternatives.8
rm -rf %{buildroot}%{_mandir}/*/man8/update-alternatives.8
rm -rf %{buildroot}%{_sysconfdir}/alternatives/
