Comment 2 for bug 1538135

Here's a build from the command line as the ubuntu user (not nodepool) on the same box using the command line the is created with nodepoold triggers the build:

TMPDIR=/mnt/ubuntu/dib_tmp DIB_IMAGE_CACHE=/mnt/ubuntu/dib_cache /usr/local/bin/disk-image-create -x -t qcow2 --no-tmpfs -o /opt/nodepool_dib/6 ubuntu vm > dib-cli-image.log 2>&1

This build succeeds without impacting the /dev .
