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>
