SYSTEMD-MACHINE-ID(1)systemd-machine-id-setupSYSTEMD-MACHINE-ID(1)NAMEsystemd-machine-id-setup - Initialize the machine ID in /etc/machine-id
SYNOPSISsystemd-machine-id-setupDESCRIPTIONsystemd-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
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.
