Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml

<title>[DHCP] Section Options</title>
|
|
|
|
<para>This section configures the DHCP Unique Identifier (DUID) value used by DHCP
|
|
protocol. DHCPv6 client protocol sends the DHCP Unique Identifier and the interface
|
|
Identity Association Identifier (IAID) to a DHCP server when acquiring a dynamic IPv6
|
|
address. DHCPv4 client protocol sends IAID and DUID to the DHCP server when acquiring
|
|
a dynamic IPv4 address if <option>ClientIdentifier=duid</option>. IAID and DUID allows
|
|
a DHCP server to uniquely identify the machine and the interface requesting a DHCP IP.
|
|
To configure IAID and ClientIdentifier, see
|
|
<citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
