Hi all,
  I am writing a module to manage MySQL/MariaDB with Galera extensions and 
have run into a problem I don't seem to be able to figure out.

Error: Could not apply complete catalog: Found 1 dependency cycle:
(File[/etc/mysql/conf.d/wsrep.cnf] => Service[mysqld] => 
Class[Mysql::Server] => Class[Mysql::Config] => File[/etc/mysql/conf.d] => 
File[/etc/mysql/conf.d/wsrep.cnf])
Cycle graph written to /var/lib/puppet/state/graphs/cycles.dot.

A cut down version of my puppet file is:
class galera::server (
 #<snip>
) inherits mysql {

  #<snip>

  class { 'mysql::server':
    config_hash  => $config_hash,
    package_name => $server_package_name,
    service_name => $service_name,
  }

  #<snip>

  file { '/etc/mysql/conf.d/wsrep.cnf' :
    ensure  => present,
    mode    => '0644',
    owner   => 'root',
    group   => $root_group,
    content => template('galera/wsrep.cnf.erb'),
    #require => File['/etc/mysql/conf.d/'],
    notify  => Service['mysqld']
  }
}

I am using the current puppetlabs-mysql (v0.9.0) from puppet forge.
https://github.com/puppetlabs/puppetlabs-mysql/tree/master/manifests

I need the file to go in after the /etc/mysql/conf.d/ resource is complete, 
but before the service is started. 

The /etc/mysql/conf.d/ resource is listed in mysql::config as:
class mysql::config(
  # <snip>
  $purge_conf_dir                   = $mysql::purge_conf_dir,
) inherits mysql {
  

  file { '/etc/mysql/conf.d':
    ensure  => directory,
    mode    => '0755',
    recurse => $purge_conf_dir,
    purge   => $purge_conf_dir,
  }
}

class mysql(
  #<snip>
  $purge_conf_dir        = $mysql::params::purge_conf_dir,
  #<snip>
) {
  #<snip>
}

class mysql::params {
 # <snip>
  $purge_conf_dir      = false 
 #<snip>
}

Does it have something to do with the recurse/purge metaparameters?  The 
defaults seem to be set as false.

Full puppet file attached and dot file from --graph.

Any light into this would be great.

Adam
