machine-info
Local machine information file
/etc/machine-info
Description
The /etc/machine-info file contains
machine metadata.
The format of machine-info is a newline-separated list of environment-like
shell-compatible variable assignments, ignoring comments and empty lines. It is possible to source the
configuration from shell scripts, however, beyond mere variable assignments no shell features are
supported, allowing applications to read the file without implementing a shell compatible execution
engine. See
os-release5 for a
detailed description of the format.
/etc/machine-info contains metadata about the machine that is set by the user
or administrator. The settings configured here have the highest precedence. When not set, appropriate
values may be determined automatically, based on the information about the hardware or other
configuration files. It is thus completely fine for this file to not be present.
You may use
hostnamectl1
to change the settings of this file from the command line.
Options
The following machine metadata parameters may be set using
/etc/machine-info:
PRETTY_HOSTNAME=
A pretty human-readable UTF-8 machine
identifier string. This should contain a name like
Lennart's Laptop which is useful to present
to the user and does not suffer by the syntax limitations of
internet domain names. If possible, the internet hostname as
configured in /etc/hostname should be
kept similar to this one. Example: if this value is
Lennart's Computer an Internet hostname of
lennarts-computer might be a good choice.
If this parameter is not set, an application should fall back
to the Internet hostname for presentation
purposes.
ICON_NAME=
An icon identifying this machine according to
the XDG
Icon Naming Specification. If this parameter is not
set, an application should fall back to
computer or a similar icon
name.
CHASSIS=
The chassis type. Currently, the following
chassis types are defined:
desktop,
laptop,
convertible,
server,
tablet,
handset,
watch, and
embedded,
as well as the special chassis types
vm and
container for
virtualized systems that lack an immediate physical chassis.
Note that most systems allow detection of the chassis type automatically (based on firmware
information or suchlike). This setting should only be used to override a misdetection or to manually
configure the chassis type where automatic detection is not available.
DEPLOYMENT=
Describes the system deployment environment.
One of the following is suggested:
development,
integration,
staging,
production.
LOCATION=
Describes the system location if applicable
and known. Takes a human-friendly, free-form string. This may
be as generic as Berlin, Germany or as
specific as Left Rack, 2nd Shelf.
KERNEL_INSTALL_MACHINE_ID=
Specifies the installation-specific installation directory
kernel-install should use. The value must be a valid machine ID (32 hexadecimal
characters). This would generally be the original machine-id that was used when the boot loader
entries for this installation were first added. When not set, the current value of
machine-id5
will be used.
VENDOR=
Specifies the hardware vendor. If unspecified, the hardware vendor set in DMI
or hwdb will be used.
MODEL=
Specifies the hardware model. If unspecified, the hardware model set in DMI or
hwdb will be used.
Example
PRETTY_HOSTNAME="Lennart's Tablet"
ICON_NAME=computer-tablet
CHASSIS=tablet
DEPLOYMENT=production
