Add the 'convertible' type to the set of allowed chassis. This applies to all devices that can be transformed by the user from laptop style to tablet style. This does not add any auto-detection, yet. It only makes 'set-chassis' accept 'convertible' as valid input.

|
<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 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>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>

<listitem><para>Set 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 host names are set, and the pretty host name is left untouched.</para>
