This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.

<para>The <filename>/etc/machine-info</filename> file contains

machine metadata.</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 metadata
|
|
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>

<para>You may use

<listitem><para>A pretty human-readable UTF-8 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 hostname 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 hostname of
|
|
<literal>lennarts-computer</literal> might be a good choice.

If this parameter is not set, an application should fall back

<literal>vm</literal> and

virtualized systems that lack an immediate physical chassis.

Note that many systems allow detection of the chassis type
|

automatically (based on firmware information or suchlike).

This setting (if set) shall take precedence over automatically

detected information and is useful to override misdetected

automatic detection is not available.</para></listitem>
