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>The <filename>/etc/machine-info</filename> file contains
machine metadata.</para>
<para>The basic file format of <filename>machine-info</filename>
is a newline-separated list of environment-like shell-compatible
variable assignments. It is possible to source the configuration
from shell scripts, however, beyond mere variable assignments no
shell features are supported, allowing applications to read the
file without implementing a shell compatible execution
engine.</para>
<para><filename>/etc/machine-info</filename> contains metadata
about the machine that is set by the user or administrator.</para>
<para>Depending on the operating system other configuration files
might be checked for machine information as well, however only as
fallback.</para>
<para>You may use
<citerefentry><refentrytitle>hostnamectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
to change the settings of this file from the command line.</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>The following machine metadata parameters may be set using
<filename>/etc/machine-info</filename>:</para>
<variablelist>
<varlistentry>
<term><varname>PRETTY_HOSTNAME=</varname></term>
<listitem><para>A pretty human-readable UTF-8 machine
identifier string. This should contain a name like
<literal>Lennart's Laptop</literal> which is useful to present
to the user and does not suffer by the syntax limitations of
internet domain names. If possible, the internet hostname as
configured in <filename>/etc/hostname</filename> should be
kept similar to this one. Example: if this value is
<literal>Lennart's Computer</literal> an Internet hostname of
<literal>lennarts-computer</literal> might be a good choice.
If this parameter is not set, an application should fall back
to the Internet host name for presentation
purposes.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>ICON_NAME=</varname></term>
<listitem><para>An icon identifying this machine according to
the <ulink
url="http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html">XDG
Icon Naming Specification</ulink>. If this parameter is not
set, an application should fall back to
<literal>computer</literal> or a similar icon
name.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>CHASSIS=</varname></term>
<listitem><para>The chassis type. Currently, the following
chassis types are defined:
<literal>desktop</literal>,
<literal>laptop</literal>,
<literal>convertible</literal>,
<literal>server</literal>,
<literal>tablet</literal>,
<literal>handset</literal>,
<literal>watch</literal>, and
<literal>embedded</literal>,
as well as the special chassis types
<literal>vm</literal> and
<literal>container</literal> for
virtualized systems that lack an immediate physical chassis.
Note that many systems allow detection of the chassis type
automatically (based on firmware information or suchlike).
This setting (if set) shall take precedence over automatically
detected information and is useful to override misdetected
configuration or to manually configure the chassis type where
automatic detection is not available.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>DEPLOYMENT=</varname></term>
<listitem><para>Describes the system deployment environment.
One of the following is suggested:
<literal>development</literal>,
<literal>integration</literal>,
<literal>staging</literal>,
<literal>production</literal>.
</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>LOCATION=</varname></term>
<listitem><para>Describes the system location if applicable
and known. Takes a human-friendly, free-form string. This may
be as generic as <literal>Berlin, Germany</literal> or as
specific as <literal>Left Rack, 2nd Shelf</literal>.
