PackageKit comes with Smart support disabled by default. How Smart will be available in Mageia: bug 1426 . I request the inclusion of a separate package: PackageKit-smart to enable use of smart as a backend in Packagekit.

I did a packagekit.spec as a suggestion. And it worked well.

The changes were:
 
%package smart
Summary: PackageKit SMART backend
Group: System Environment/Libraries
Requires: smart
Requires: %{name} = %{version}-%{release}
 
%description smart
A backend for PackageKit to enable SMART functionality.

and:

        --enable-smart --enable-urpmi --enable-introspection \

and:

 
%files smart
%defattr(-,root,root,-)
%{_libdir}/packagekit-backend/libpk_backend_smart.so
%dir %{_datadir}/PackageKit/helpers/smart
%{_datadir}/PackageKit/helpers/smart/*
