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. 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
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
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
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 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.
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
Specifies the installation-specific installation
should use. The value must be a valid machine
ID (32 hexadecimal characters). This would generally be the original
machine-id that was used when the boot loader entries for this installation
were first added. When not set, the current value of machine-id(5)
