<H2>DESCRIPTION</H2>
|
|
|
|
<P>
|
|
|
|
The
|
|
/etc/hostname
|
|
file configures the name of the local system that is set during boot using the
|
|
<B><A HREF="/cgi-bin/man/man2html?2+sethostname">sethostname</A></B>(2)
|
|
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.
|
|
<P>
|
|
|
|
You may use
|
|
<B><A HREF="/cgi-bin/man/man2html?1+hostnamectl">hostnamectl</A></B>(1)
|
|
to change the value of this file during runtime from the command line. Use
|
|
<B><A HREF="/cgi-bin/man/man2html?1+systemd-firstboot">systemd-firstboot</A></B>(1)
|
|
to initialize it on mounted (but not booted) system images.
