<title>Description</title>
|
|
|
|
<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

|
|
Interface</ulink>.</para>
