Another details about what image to pull/use when just using `distrobox create
foo` (without specifying the --image option):
> $ cat /usr/etc/distrobox/distrobox.conf
> container_image="registry.opensuse.org/opensuse/tumbleweed:latest"
> container_image_default="registry.opensuse.org/opensuse/tumbleweed:latest"
> container_name="tumbleweed"
> container_manager="autodetect"
> non_interactive="true"
