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>Description</title>

<para><filename>systemd-cryptsetup-generator</filename> is a

generator that translates <filename>/etc/crypttab</filename> into
|
|
native systemd units early at boot and when configuration of the
|
|
system manager is reloaded. This will create

|
<citerefentry><refentrytitle>systemd-cryptsetup@.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
units as necessary.</para>
