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.

       Depending on the operating system other configuration files might be
       checked for machine information as well, however only as fallback.

       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 host name
           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 many systems allow detection
           of the chassis type automatically (based on firmware information or
           suchlike). This setting (if set) shall take precedence over
           automatically detected information and is useful to override
           misdetected configuration 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
