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.

       Similarly, 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
       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

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