docker error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link

docker-cross-device-link.md

on linux 4.19, I get

error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link

when trying to install stuff on a ubuntu docker container. this seems to be an issue with metacopy https://www.spinics.net/lists/linux-unionfs/msg06109.html

issue can be worked around by running

echo N | sudo tee /sys/module/overlay/parameters/metacopy

For more details: docker/for-linux#480

Thanks!
