- <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 default 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>

- not booted) system images.</para>

- special characters. This ensures that

- always closely related while still
