docker fails to start no more loopback devices

sudo pacman -S docker
sudo systemctl start docker

And it fails with

There are no more loopback devices available.
[graphdriver] prior storage driver devicemapper failed: loopback attach failed

How do I get the Docker daemon to start?

Re: docker fails to start no more loopback devices

Your docker configuration uses the devicemapper storage driver for some reason.

Change your config to use the overlay driver
