Closed issue by kernle32dll on void-packages repository

https://github.com/void-linux/void-packages/issues/19202

Description:
The commit https://github.com/void-linux/void-packages/commit/ec709f9e09458bb1707a4136c1d4635ca11b0e7a did not only update docker, but enforced the `overlay2` storage driver. While this is a fine default, it can actually break docker on `btrfs` file systems.

From the [Dockerd documentation](https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-storage-driver):

> Note: Both overlay and overlay2 are currently unsupported on btrfs or any Copy on Write filesystem and should only be used over ext4 partitions.

Even if not breaking, its an un-intuitive change, if you don't happen to use `overlay2` previously. It took me a good while to understand why all of my images and volumes were gone - which was due to the change of the storage driver.

Its easy to fix locally - just remove the `storage-driver` line from `/etc/docker/daemon.json`. But this should be removed in the package, too - IMO.
