Zbigniew Jędrzejewski-Szmek fdbbee37d5 man: drop unused <authorgroup> tags from man sources
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.

<title>Description</title>
<para><filename>systemd-update-done.service</filename> is a
service that is invoked as part of the first boot after the vendor
operating system resources in <filename>/usr</filename> have been
updated. This is useful to implement offline updates of
<filename>/usr</filename> which might require updates to
<filename>/etc</filename> or <filename>/var</filename> on the
following boot.</para>
<para><filename>systemd-update-done.service</filename> updates the
file modification time (mtime) of the stamp files
<filename>/etc/.updated</filename> and
<filename>/var/.updated</filename> to the modification time of the
<filename>/usr</filename> directory, unless the stamp files are
already newer.</para>
<para>Services that shall run after offline upgrades of
<filename>/usr</filename> should order themselves before
<filename>systemd-update-done.service</filename>, and use the
<varname>ConditionNeedsUpdate=</varname> (see
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>)
condition to make sure to run when <filename>/etc</filename> or
<filename>/var</filename> are older than <filename>/usr</filename>
according to the modification times of the files described above.
This requires that updates to <filename>/usr</filename> are always
followed by an update of the modification time of
<filename>/usr</filename>, for example by invoking
<citerefentry project='man-pages'><refentrytitle>touch</refentrytitle><manvolnum>1</manvolnum></citerefentry>
on it.</para>
