Install bacula client 5.2.x by yum

This will install Bacula client 5.2.12 from dassit repo

cd /etc/yum.repos.d/
wget http://download.opensuse.org/repositories/home:/dassit:/bacula/CentOS_CentOS-6/home:dassit:bacula.repo
yum install bacula-client

Adapted from http://www.dass-it.de/download/bacula, but run yum install bacula does not install the bacula client.
