{{#
  A wrapper over the Ansible lineinfile module. This handles the most common
  options for us. regex is optional and when blank, it won't be included in
  the Ansible script; this allows arbitrary additions to files. new_line will
  only be passed when state is present. with_items will be specified only if
  non-empty, allowing for iterating through a variable of content (with the
  appropriate macro-based path). register will be specified only if non-empty,
  allowing for saving the output of this lineinfile module. check_mode allows
  an idempotent way to gather output, or run a task without changes. Useful when
  calling the ansible_only_lineinfile macro to handle deduplication of values.

  Note that all string-like parameters are single quoted in the YAML.

    Make sure that a line with a specific PAM module is present with the correct control.
    If the line is not present, it will be included after the regex informed in the "after_match"
    parameter. If the "after_match" parameter is empty, the line will be included at the end of
    the file informed in the "pam_file" parameter.
    If the line was already present, but with a different control, the control will be updated.
    Note: If there are multiple lines matching the "group" + "module", no lines will be updated.
    Instead, a new line will be included after the regex informed in "after_match" or at the
    end of file if "after_match" parameter is empty or there is no match.
    This is a conservative safeguard for improper use of this macro in rare cases of modules
    configured by multiple lines, like pam_sss.so, pam_faillock.so and pam_lastlog.so. In some
    situations, these special modules may have similar lines sharing the same "group" and "module".
    For these specific cases, this macro is not recommened without careful tests to make sure the

    Create a list of paths composed by root directories and mount points representing local file systems.
    This list excludes all local directories and mount points using known remote file systems.
    It also excludes local directories and mount points with pseudo file systems. The list of paths
    created by this macro can be used to efficiently locate local files or directories in a system.
