  61
  62     <para><command>systemd-networkd</command> is a system service that
  63     manages networks. It detects and configures network devices as
  64     they appear, as well as creating virtual network devices.</para>
  65
  66     <para>To configure low-level link settings independently of
  67     networks, see
  68     <citerefentry><refentrytitle>systemd.link</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
  69
  70     <para>Network configurations applied before networkd is started
  71     are not removed, and static configuration applied by networkd is
  72     not removed when networkd exits. Dynamic configuration applied by
  73     networkd may also optionally be left in place on shutdown. This
  74     ensures restarting networkd does not cut the network connection,
  75     and, in particular, that it is safe to transition between the
  76     initrd and the real root, and back.</para>

  80     <para>The configuration files are read from the files located in the
  81     system network directory <filename>&rootlibexecdir;/network</filename>,
  82     the volatile runtime network directory
  83     <filename>/run/systemd/network</filename> and the local administration
  84     network directory <filename>&pkgsysconfdir;/network</filename>.</para>
