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>

76   <refsect1><title>Configuration Files</title>
77     <para>The configuration files are read from the files located in the
78     system network directory <filename>/usr/lib/systemd/network</filename>,

80     <filename>/run/systemd/network</filename> and the local administration
81     network directory <filename>/etc/systemd/network</filename>.</para>

84     files, see
85     <citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
86     and virtual network devices are configured in
