Vmgen(1) General Commands Manual Vmgen(1)NAME
vmgen - a tool for writing fast and efficient interpreters
SYNOPSIS
vmgen INPUTFILE
DESCRIPTION
Vmgen is a tool for writing efficient interpreters. It takes a simple virtual machine description and generates efficient C code for deal-
ing with the virtual machine code in various ways (in particular, executing it). The run-time efficiency of the resulting interpreters is
usually within a factor of 10 of machine code produced by an optimizing compiler.
The main documentation for vmgen is in info format. Please use info vmgen for the complete documentation on vmgen.

SYSTEMD-MACHINE-ID(1) systemd-machine-id-setup SYSTEMD-MACHINE-ID(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.
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
This tool does not take any options or arguments.
EXIT STATUS
On success 0 is returned, a non-zero failure code otherwise.
