當文件內容沒有變化時跳過傀儡函數

Question

當文件內容沒有變化時，我想跳過某些exec和文件資源。其文件和業務組合...... 例如工作，

file { 'configfile.cfg': 
    ensure => file, 
    path => '/etc/configfile.cfg', 
    mode => '0644', 
    owner => 'root', 
    group => 'root', 
    content => template($template_file), 
    require => Package[$main_package], 
    notify => Service[$service], 

    } 

    service { $service: 
    ensure  => $ensure, 
    enable  => $enable, 
    hasrestart => true, 
    hasstatus => true, 
    require => [ Package[$main_package], File['configfile.cfg'] ], 

    } 

上面的代碼工作正常。服務只有當它檢測到/etc/configfile.cfg任何變化重新啓動..

但我下面的文件和exec組合相同的方法，但它不工作....請看下面的代碼

exec { 'purge-config-files': 
     before => [File["${config_file_service}"], File["${config_file_host}"]], 
     command => "/bin/rm -f ${baseconfigdir}/*", 
     notify => Domain_ip_map[$domain_ip_map_titles], 
} 

file { 'deployconfig.cfg': 
      ensure => file, 
      path => '/home/path/deployconfig.cfg', 
      mode => '0644', 
      owner => 'root', 
      group => 'root', 
      content => "test", 
      notify => Exec['purge-config-files'], 
} 

此代碼不按預期方式工作。即使 /home/path/deployconfig.cfg中沒有更改，Exec ['purge-config-files']始終爲 正在執行......可能是因爲這個原因？

我找到了答案

exec { 'purge-config-files': 
     before => [File["${config_file_service}"], File["${config_file_host}"]], 
     command => "/bin/rm -f ${baseconfigdir}/*", 
     notify => Domain_ip_map[$domain_ip_map_titles], 
     subscribe=> File['deployconfig.cfg'], 
     refreshonly => true, 
} 

我忘了訂閱和refreshonly
