machine-info — Local machine information file
/etc/machine-info file contains
The basic file format of
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
/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
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
/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
An icon identifying this machine according to
Icon Naming Specification. If this parameter is not
set, an application should fall back to
computer" or a similar icon
The chassis type. Currently, the following
chassis types are defined:
as well as the special chassis types
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:
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".
