Zbigniew Jędrzejewski-Szmek 11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

<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>
