Standard devices

Incus provides each instance with the basic devices that are required for a standard POSIX system to work. These devices aren’t visible in the instance or profile configuration, and they may not be overridden.

The standard devices are:

Any other devices must be defined in the instance configuration or in one of the profiles used by the instance. The default profile typically contains a network interface that becomes eth0 in the instance.
