MySQL on fedora 16/17 has a package mysql-libs. This should be
obsoleted by MariaDB-shared, but there is a missing provision in
which makes you have to force install the package and also reports
as inconsistencies in dependencies after install.
Also installation of MariaDB-shared fails as it is not marked as a
package obsoleting package mysql-libs
This provides list should also include:
mysql-libs = 5.5.28a-1 <not sure of exact string to use here>
