Comment 5 for bug 1210160

Hmm...works for me:

localadmin@compute01:~$ grep -A6 'override_options:' /etc/puppet/data/hiera_data/user.common.yaml
mysql::server::override_options:
  mysqld:
    bind-address: 192.168.255.134
    max-connections: 8192
    max_connect_errors: 4294967295
  isamchk:
    key_buffer_size: 64M
localadmin@compute01:~$ grep max-connections /etc/mysql/my.cnf
max-connections = 8192
localadmin@compute01:~$

mysql> show variables where Variable_name = 'max_connections';
+-----------------+-------+
| Variable_name | Value |
