SYSTEMD-MACHINE-ID(1)					     systemd-machine-id-setup					     SYSTEMD-MACHINE-ID(1)

NAME

       systemd-machine-id-setup - Initialize the machine ID in /etc/machine-id

SYNOPSIS

       systemd-machine-id-setup

DESCRIPTION

       systemd-machine-id-setup may be used by system installer tools to initialize the machine ID stored in /etc/machine-id at install time with
       a randomly generated ID. See machine-id(5) for more information about this file.

       This tool will execute no operation if /etc/machine-id is already initialized.

       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
       /etc/machine-id.

       If run inside a KVM virtual machine and a UUID is passed via the -uuid 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.

       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 Container Interface[1].

OPTIONS

       This tool does not take any options or arguments.

EXIT STATUS

       On success 0 is returned, a non-zero failure code otherwise.
