The object id is the name of the architecture accepted by +`dpkg`, which should be added or removed. + +If the architecture is not setup on the system, it adds a new architecture as a +new foreign architecture in `dpkg`. Then, it updates the apt package index to +make packages from the new architecture available. + +If the architecture should be removed, it will remove it if it is not the base +architecture on where the system was installed on. Before it, it will purge +every package based on the "to be removed" architecture via `apt` to be able to +remove the selected architecture. + + +REQUIRED PARAMETERS +------------------- +None. + + +OPTIONAL PARAMETERS +------------------- +state + ``present`` or ``absent``.
