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

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