enroot import fails on directory exists

[dfisk]

My container has a predefined user 'nemo' and a both USER nemo and WORKDIR /workspace/nemo statements in the Dockerfile. When attempting to import this container from the dockerd it fails with:

[INFO] Extracting image content...
mkdir: cannot create directory ‘rootfs/workspace/nemo’: File exists

This should not be a fatal error; please use 'mkdir -p' not 'mkdir' to avoid this innocuous condition as a show stopper. Thanks!
