nginx.conf template is hardcoded - override of for example nginx username is not possible

[c33s]

class nginx::config () inherits nginx {

  assert_private("Use of private class ${name} by ${caller_module_name}")

  file { "${nginx::install_location}/nginx.conf":
    ensure  => file,
    content => epp("${module_name}/nginx.conf.epp",
      {
        'install_location' => $nginx::install_location,
      }
    ),
  }
