NAME¶

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

SYNOPSIS¶

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].
