        <para>
          NetworkManager is based on the concept of connection profiles that contain
          network configuration (see <citerefentry><refentrytitle>nm-settings</refentrytitle>
          <manvolnum>5</manvolnum></citerefentry> for details). The profiles can be
          stored in various formats. NetworkManager uses plugins for reading and writing
          the data. The plugins can be configured in <citerefentry>
          <refentrytitle>NetworkManager.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
        </para>
        <para>
          The <emphasis>keyfile</emphasis> plugin is the generic plugin that supports all
          the connection types and capabilities that NetworkManager has. The files are
          in a .ini-style format and located in <filename>/etc/NetworkManager/system-connections/</filename>,
          <filename>/usr/lib/NetworkManager/system-connections/</filename> and
          <filename>/run/NetworkManager/system-connections/</filename>.
          This plugin is always enabled and will automatically be used to store
          any connections that are not supported by any other active plugin.
          For security, it will ignore files that are readable or writable by any user
          other than 'root' since private keys and passphrases may be stored
          in plaintext inside the file.
        </para>

      <refsect1 id='file_format'><title>File Format</title>
        <para>
          The <emphasis>keyfile</emphasis> config format is a simple .ini-style
          format. It consists of sections (groups) of key-value pairs. Each section
          corresponds to a setting name as described in the settings specification
          (<citerefentry><refentrytitle>nm-settings</refentrytitle>
          <manvolnum>5</manvolnum></citerefentry>). Each configuration key/value
          pair in the section is one of the properties listed in the settings
          specification. The majority of properties of the specification is written
          in the same format into the <emphasis>keyfile</emphasis> too. However
          some values are inconvenient for people to use. These are stored in the
          files in more readable ways. These properties are described below.
          An example could be IP addresses that are not written as integer arrays,
          but more reasonably as "1.2.3.4/12 1.2.3.254".
          More information of the generic key file format can be found at
          <ulink url="https://developer.gnome.org/glib/stable/glib-Key-value-file-parser.html#glib-Key-value-file-parser.description">
          GLib key file format</ulink> (Lines beginning with a '#' are comments,
          lists are separated by character <literal>;</literal> etc.).
        </para>
        <para>
          Users can create or modify the <emphasis>keyfile</emphasis> connection files
          manually, even if that is not the recommended way of managing the profiles.
          However, if they choose to do that, they must inform NetworkManager about
          their changes (see <emphasis>monitor-connection-file</emphasis> in
          <citerefentry><refentrytitle>nm-settings</refentrytitle><manvolnum>5</manvolnum>
          </citerefentry> and <emphasis>nmcli con (re)load</emphasis>).

          <emphasis>keyfile</emphasis> plugin variables for the majority of NetworkManager
          properties have one-to-one mapping. It means a NetworkManager property is stored

          There are several exceptions to this rule, mainly for making keyfile syntax easier
          for humans. The exceptions handled specially by <emphasis>keyfile</emphasis>
          plugin are listed below. Refer to

            Some of the NetworkManager setting names are somewhat hard to type or remember. Therefore
