The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

<title>Description</title>
|
|
|
|
<para><command>systemd-networkd</command> is a system service that
|
|
manages networks. It detects and configures network devices as
|
|
they appear, as well as creating virtual network devices.</para>
|
|
|
|
<para>To configure low-level link settings independently of
|
|
networks, see
|
|
<citerefentry><refentrytitle>systemd.link</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
|
|
|
|
<para><command>systemd-networkd</command> will create network devices based
|
|
on the configuration in
|
|
<citerefentry><refentrytitle>systemd.netdev</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
files, respecting the [Match] sections in those files.</para>
|
|
|
|
<para><command>systemd-networkd</command> will manage network addresses and
|
|
routes for any link for which it finds a <filename>.network</filename> file
|
|
with an appropriate [Match] section, see
|
|
<citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
|
|
For those links, it will flush existing network addresses and routes when
|
|
bringing up the device. Any links not matched by one of the
|
|
<filename>.network</filename> files will be ignored. It is also possible to
|
|
explicitly tell <filename>systemd-networkd</filename> to ignore a link by
|
|
using <varname>Unmanaged=yes</varname> option, see
|
|
<citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
|
|
</para>
|
|
|
|
<para>When <filename>systemd-networkd</filename> exits, it generally leaves
|
|
existing network devices and configuration intact. This makes it possible to
|
|
transition from the initramfs and to restart the service without breaking
|
|
connectivity. This also means that when configuration is updated and
|
|
<filename>systemd-networkd</filename> is restarted, netdev interfaces for
|
|
which configuration was removed will not be dropped, and may need to be
|
|
cleaned up manually.</para>

<refsect1><title>Configuration Files</title>
|
|
<para>The configuration files are read from the files located in the
|
|
system network directory <filename>/usr/lib/systemd/network</filename>,
|
|
the volatile runtime network directory
|
|
<filename>/run/systemd/network</filename> and the local administration
|
|
network directory <filename>/etc/systemd/network</filename>.</para>
|
|
|
|
<para>Networks are configured in <filename>.network</filename>
|
|
files, see
|
|
<citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
|
|
and virtual network devices are configured in
|
|
<filename>.netdev</filename> files, see
|
|
<citerefentry><refentrytitle>systemd.netdev</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
