MACHINE-INFO(5) machine-info MACHINE-INFO(5)
NAME
machine-info - Local machine information file
SYNOPSIS
/etc/machine-info
DESCRIPTION
The /etc/machine-info file contains machine metadata.
The basic file format of machine-info is a newline-separated list of
environment-like shell-compatible variable assignments. 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.
/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 hostnamectl(1) 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[1]. 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".
EXAMPLE
PRETTY_HOSTNAME="Lennart's Tablet"
ICON_NAME=computer-tablet
CHASSIS=tablet
DEPLOYMENT=production
