  57     <title>Description</title>
  58
  59     <para><command>systemd-networkd</command> is a system service that
  60     manages networks. It detects and configures network devices as
  61     they appear, as well as creating virtual network devices.</para>
  62
  63     <para>To configure low-level link settings independently of
  64     networks, see
  65     <citerefentry><refentrytitle>systemd.link</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
  66
  67     <para>Network configurations applied before networkd is started
  68     are not removed, and static configuration applied by networkd is
  69     not removed when networkd exits. Dynamic configuration applied by
  70     networkd may also optionally be left in place on shutdown. This
  71     ensures restarting networkd does not cut the network connection,
  72     and, in particular, that it is safe to transition between the
  73     initrd and the real root, and back.</para>
