Percona Xtradb Cluster, not "mysql percona"

I'm actually more confused now than before I read this. The use of
numbers is just making my head spin.

It can be stated this way I think:

On RPM systems, use MariaDB Galera packages.
    If packages are in the distro, use distro packages. If packages are
    not in the distro, use RDO packages.

On DEB systems, use Percona XtraDB Cluster packages.
    If packages are in the distro, use distro packages. If packages are
    not in the distro, use upstream packages.

If anything doesn't match those principles, it is a bug.
