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
/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
The following machine metadata parameters may be set using
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.
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", "staging",
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".
