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].
       Use systemd-firstboot(1) to initialize the machine ID on mounted (but
       not booted) system images.
OPTIONS
       The following options are understood:
       --root=root
           Takes a directory path as an argument. All paths will be prefixed
           with the given alternate root path, including config search paths.
       -h, --help
           Print a short help text and exit.
       --version
           Print a short version string and exit.
EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise.
