    type: str
  quadlet_file_mode:
    description:
      - The permissions of the quadlet file.
      - The O(quadlet_file_mode) can be specied as octal numbers or as a symbolic mode (for example, V(u+rwx) or V(u=rw,g=r,o=r)).
        For octal numbers format, you must either add a leading zero so that Ansible's YAML parser knows it is an
        octal number (like V(0644) or V(01777)) or quote it (like V('644') or V('1777')) so Ansible receives a string
        and can do its own conversion from string into number. Giving Ansible a number without following one of these
        rules will end up with a decimal number which will have unexpected results.
      - If O(quadlet_file_mode) is not specified and the quadlet file B(does not) exist, the default V('0640') mask will be used
        when setting the mode for the newly created file.
      - If O(quadlet_file_mode) is not specified and the quadlet file B(does) exist, the mode of the existing file will be used.
      - Specifying O(quadlet_file_mode) is the best way to ensure files are created with the correct permissions.
    type: raw
    required: false

    description:
      - Options for the quadlet file. Provide missing in usual network args
        options as a list of lines to add.
