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", "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
