Comment # 4 on bug 1102224 from George Anchev

Actually it seems the file was simply renamed, not removed. Here is a
workaround which lead to successful starting of the service:

# ln -s libmysqlclient.so libmysqlclient.so.18
# systemctl start bacula-dir.service
# systemctl status bacula-dir.service
��� bacula-dir.service - LSB: bacula director
