<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. Comments (lines starting with a `#') are ignored.
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>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>
