machine-info - Local machine information file
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.
The following machine metadata parameters may be set using /etc/machine-info:
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
An icon identifying this machine according to the XDG
Icon Naming Specification. If this parameter is not set, an application
should fall back to "computer" or a similar icon name.
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.
Describes the system deployment environment. One of the
following is suggested: "development", "integration",
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
