<title>Description</title>
<para>The <filename>/etc/hostname</filename> file
configures the name of the local system that is set
during boot using the
<citerefentry><refentrytitle>sethostname</refentrytitle><manvolnum>2</manvolnum></citerefentry>
system call. It should contain a single
newline-terminated hostname string. The
hostname may be a free-form string up to 64 characters
in length; however, it is recommended that it consists
only of 7-bit ASCII lower-case characters and no spaces or dots,
and limits itself to the format allowed for DNS domain
name labels, even though this is not a
strict requirement.</para>
<para>Depending on the operating system, other
configuration files might be checked for configuration
of the hostname as well, however only as fallback.</para>
<para>You may use
<citerefentry><refentrytitle>hostnamectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
to change the value of this file during runtime from
the command line. Use
<citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
to initialize it on mounted (but not booted) system
images.</para>
