Every time I try building with docker or fig an image (doesn't matter which one), I randomly will get
Cannot start container <containerId>: Error getting container <containerId> from driver devicemapper: Error mounting '/dev/mapper/docker-8:1-262151-<containerId>' on '/var/lib/docker/devicemapper/mnt/<containerId>': no such file or directory
Weird thing is, if I re-run it, it usually won't have the same error.
Note that I am running docker inside vagrant (ubuntu-trusty-64)
Switching to aufs storage seemed to resolve it.
I used a base image box from phusion which seems to optimize for docker.
