<title>Description</title>
<para>The <filename>/etc/hostname</filename> file
configures the name of the local system that is set
during boot, with the
<citerefentry><refentrytitle>sethostname</refentrytitle><manvolnum>2</manvolnum></citerefentry>
system call. It should contain a single
newline-terminated host name string. The
host name may be a free-form string up to 64 characters
in length, however it is recommended that it consists
only of 7bit ASCII characters and no spaces or dots,
and limit itself to the format allowed for DNS domain
name labels, even though this is not a
requirement.</para>
<para>Depending on the operating system other
configuration files might be checked for configuration
of the host name as well, however only as fallback.</para>

<title>History</title>
<para>The simple configuration file format of
<filename>/etc/hostname</filename> originates from
Debian GNU/Linux.</para>
