install_err '/var/lib/docker exists. You need to:
systemctl stop docker
systemctl disable docker
rm -rf /var/lib/docker/*
umount /var/lib/docker
rmdir /var/lib/docker
perl -pi -e "s{^/var/lib/docker.*}{}" /etc/fstab
lvremove -f /dev/mapper/docker-vps

Then re-run rsconf. This should only happen in development environments.
