+ <title>Description</title>
+
+ <para><command>hostnamectl</command> may be used to query and
+ change the system hostname and related settings.</para>
+
+ <para>This tool distinguishes 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 used to initialize the kernel hostname at boot (e.g.
+ "lennarts-laptop"), and the transient hostname which is a fallback
+ value received from network configuration. If a static hostname is
+ set, and is valid (something other than localhost), then the
+ transient hostname is not used.</para>
+
+ <para>Note that the pretty hostname has little restrictions on the
+ characters used, while the static and transient hostnames are
+ limited to the usually accepted characters of Internet domain
+ names.</para>
+
+ <para>The static hostname is stored in
+ <filename>/etc/hostname</filename>, see
+ <citerefentry><refentrytitle>hostname</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ for more information. The pretty hostname, chassis type, and icon
+ name are stored in <filename>/etc/machine-info</filename>, see
+ <citerefentry><refentrytitle>machine-info</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
+
+ <para>Use
+ <citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ to initialize the system host name for mounted (but not booted)
+ system images.</para>

+ <command>hostnamectl</command> will print out just this
+ selected hostname.</para>
+
+ <para>If used with <command>set-hostname</command>, only the

+ 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 replacing spaces with <literal>-</literal> and
+ removing special characters. 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 host names are set, and the pretty
+ host name is left untouched.</para>
