<title>Description</title>
<para>The <filename>/etc/machine-info</filename> file
contains machine meta data.</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
meta data 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>The following machine meta data 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 UTF8 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 host name 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 host name 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>
