2.6 Overlayfs Error with Docker

Running yum install within a container on an overlayfs file system can fail with the following error:

Rpmdb checksum is invalid: dCDPT(pkg checksums): package_name

This error breaks Dockerfile builds and is a known issue upstream (see https://github.com/docker/docker/issues/10180.)

The workaround is to run touch /var/lib/rpm/* before installing the package. (Bug ID 21804564)
