This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<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>
