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