DESCRIPTION
       systemd-networkd is a system service that manages networks. It detects
       and configures network devices as they appear, as well as creating
       virtual network devices.

       To configure low-level link settings independently of networks, see
       systemd.link(5).

       Network configurations applied before networkd is started are not
       removed, and static configuration applied by networkd is not removed
       when networkd exits. Dynamic configuration applied by networkd may also
       optionally be left in place on shutdown. This ensures restarting
       networkd does not cut the network connection, and, in particular, that
       it is safe to transition between the initrd and the real root, and
       back.

CONFIGURATION FILES
       The configuration files are read from the files located in the system
       network directory /lib/systemd/network, the volatile runtime network
       directory /run/systemd/network and the local administration network
       directory /etc/systemd/network.

       Networks are configured in .network files, see systemd.network(5), and
       virtual network devices are configured in .netdev files, see
       systemd.netdev(5).
