+ <title>Description</title>
+
+ <para>The <filename>/etc/machine-info</filename> file contains
+ machine metadata.</para>
+
+ <para>The format of <filename>machine-info</filename> is a newline-separated list of environment-like
+ shell-compatible variable assignments, ignoring comments and empty lines. 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. See
+ <citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry> for a
+ detailed description of the format.</para>
+
+ <para><filename>/etc/machine-info</filename> contains metadata about the machine that is set by the user
+ or administrator. The settings configured here have the highest precedence. When not set, appropriate
+ values may be determined automatically, based on the information about the hardware or other
+ configuration files. It is thus completely fine for this file to not be present.</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>

+ <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 hostname for presentation
+ purposes.</para></listitem>
