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-backlight@.service</filename> is a service
|
|
that restores the display backlight brightness at early boot and
|
|
saves it at shutdown. On disk, the backlight brightness is stored
|
|
in <filename>/var/lib/systemd/backlight/</filename>. During
|
|
loading, if the udev property <option>ID_BACKLIGHT_CLAMP</option> is
|
|
not set to false, the brightness is clamped to a value of at
|
|
least 1 or 5% of maximum brightness, whichever is greater. This
|
|
restriction will be removed when the kernel allows user space to
|
|
reliably set a brightness value which does not turn off the
|
|
display.</para>
