  59                 <para><command>systemd-networkd</command> is a system
  60                 service that manages networks. It detects and configures
  61                 network devices as they appear, as well as creating virtual
  62                 network devices.</para>
  63
  64                 <para>To configure low-level link settings independently of
  65                 networks, see

  67
  68                 <para>Network configurations applied before networkd is started
  69                 are not removed, and static configuration applied by networkd
  70                 is not removed when networkd exits. Dynamic configuration applied by
  71                 networkd may also optionally be left in place on shutdown. This ensures
  72                 restarting networkd does not cut the network connection, and, in particular,
  73                 that it is safe to transition between the initrd and the real root,
  74                 and back.</para>
