We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

<para>The <filename>/etc/machine-info</filename> file
|
|
contains machine meta data.</para>
|
|
|
|
<para>The basic file format of
|
|
<filename>machine-info</filename> is a
|
|
newline-separated list of environment-like
|
|
shell-compatible variable assignments. It is possible
|
|
to source the configuration from shell scripts,
|
|
however, beyond mere variable assignments no shell
|
|
features are supported, allowing applications to read
|
|
the file without implementing a shell compatible
|
|
execution engine.</para>
|
|
|
|
<para><filename>/etc/machine-info</filename> contains
|
|
meta data about the machine that is set by the user or
|
|
administrator.</para>
|
|
|
|
<para>Depending on the operating system other
|
|
configuration files might be checked for machine
|
|
information as well, however only as fallback.</para>

<listitem><para>A pretty
|
|
human-readable UTF8 machine identifier
|
|
string. This should contain a name
|
|
like <literal>Lennart's
|
|
Laptop</literal> which is useful to
|
|
present to the user and does not
|
|
suffer by the syntax limitations of
|
|
internet domain names. If possible the
|
|
internet host name as configured in
|
|
<filename>/etc/hostname</filename>
|
|
should be kept similar to this
|
|
one. Example: if this value is
|
|
<literal>Lennart's Computer</literal>
|
|
an Internet host name of
|
|
<literal>lennarts-computer</literal>
|
|
might be a good choice. If this
|
|
parameter is not set an application
|
|
should fall back to the Internet host
|
|
name for presentation
|
|
purposes.</para></listitem>
