Provided by: systemd_245.4-4ubuntu3.24_amd64 bug

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
