virtualisation.docker.storageDriver
NixOS option
This option determines which Docker storage driver to use. By default it lets docker automatically choose the preferred storage driver. However, it is recommended to specify a storage driver explicitly, as docker’s default varies over versions. Changing the storage driver will cause any existing containers and images to become inaccessible.
