  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>

  65                 networks, see

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

  77                 <para>Nameservers configured in networkd, or received over DHCP
