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 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-release(5) 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 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".

       HARDWARE_VENDOR=
           Specifies the hardware vendor. If unspecified, the hardware vendor
           set in DMI or hwdb(7) will be used.

       HARDWARE_MODEL=
           Specifies the hardware model. If unspecified, the hardware model
           set in DMI or hwdb(7) will be used.

EXAMPLE
           PRETTY_HOSTNAME="Lennart's Tablet"
           ICON_NAME=computer-tablet
           CHASSIS=tablet
           DEPLOYMENT=production
