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><command>systemd-machine-id-setup</command> may be used by
|
|
system installer tools to initialize the machine ID stored in
|
|
<filename>/etc/machine-id</filename> at install time with a
|
|
randomly generated ID. See
|
|
<citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|

for more information about this file.</para>

<para>This tool will execute no operation if

<filename>/etc/machine-id</filename> is already

initialized.</para>
|

|
|
<para>If a valid D-Bus machine ID is already configured for the
|
|
system, the D-Bus machine ID is copied and used to initialize the

machine ID in <filename>/etc/machine-id</filename>.</para>

|
|
<para>If run inside a KVM virtual machine and a UUID is passed via
|
|
the <option>-uuid</option> option, this UUID is used to initialize
|
|
the machine ID instead of a randomly generated one. The caller

must ensure that the UUID passed is sufficiently unique and is
|
|
different for every booted instanced of the VM.</para>
|
|
|
|
<para>Similar, if run inside a Linux container environment and a
|
|
UUID is set for the container this is used to initialize the

machine ID. For details see the documentation of the <ulink
