+    and this tool distinguish three different hostnames: the high-level "pretty" hostname which might include
+    all kinds of special characters (e.g. "Lennart's Laptop"), the "static" hostname which is the
+    user-configured hostname (e.g. "lennarts-laptop"), and the transient hostname which is a fallback value
+    received from network configuration (e.g. "node12345678"). If a static hostname is set to a valid value,
+    then the transient hostname is not used.</para>
+
+    <para>Note that the pretty hostname has little restrictions on the characters and length used, while the static and
+    transient hostnames are limited to the usually accepted characters of Internet domain names, and 64 characters at
+    maximum (the latter being a Linux limitation).</para>
+
+    <para>Use
+    <citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry> to
+    initialize the system hostname for mounted (but not booted) system images.</para>

+    <title>Commands</title>
+
+    <para>The following commands are understood:</para>
+
+    <variablelist>
+      <varlistentry>
+        <term><command>status</command></term>
+
+        <listitem><para>Show system hostname and related information. If no command is specified,
+        this is the implied default.</para></listitem>
+      </varlistentry>
+
+      <varlistentry>
+        <term><command>hostname</command> [<replaceable>NAME</replaceable>]</term>
+
+        <listitem><para>If no argument is given, print the system hostname. If an
+        optional argument <replaceable>NAME</replaceable> is provided then the command changes the
+        system hostname to <replaceable>NAME</replaceable>. By default, this will alter the
+        pretty, the static, and the transient hostname alike; however, if one or more of <option>--static</option>,
+        <option>--transient</option>, <option>--pretty</option> are used, only the selected hostnames are changed. If
+        the pretty hostname is being set, and static or transient are being set as well, the specified hostname will be
+        simplified in regards to the character set used before the latter are updated. This is done by removing special
+        characters and spaces. This ensures that the pretty and the static hostname are always closely related while
+        still following the validity rules of the specific name. This simplification of the hostname string is not done
+        if only the transient and/or static hostnames are set, and the pretty hostname is left untouched.</para>
+
+        <para>The static and transient hostnames must each be either a single DNS label (a string composed of
+        7-bit ASCII lower-case characters and no spaces or dots, limited to the format allowed for DNS domain
+        name labels), or a sequence of such labels separated by single dots that forms a valid DNS FQDN. The
+        hostname must be at most 64 characters, which is a Linux limitation (DNS allows longer names).</para></listitem>

+        graphical applications to visualize this host. The icon name
+        should follow the <ulink
