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.

           Added in version 197.

       DEPLOYMENT=
           Describes the system deployment environment. One of the following is suggested:
           "development", "integration", "staging", "production".

           Added in version 216.

       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".

           Added in version 216.

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

           Added in version 251.

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

           Added in version 251.

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