Comparing ACL on Puppet 4 / Puppet 5

Need to collect

  • Output of puppet resource acl c:\windows
  • Output of test.pp manifest run (make sure c:\test directory is not present prior)
    • What's up with initial application always showing an empty []? (This appears to be a separate bug in all Puppet versions)
file { 'c:/test': ensure => 'directory' } ~>
acl { 'c:/test':
 purge => 'true',
