FS Stays Mounted

[sabjorn]

Currently running this docker container sequentially will result in persistence of the previously mounted image.

i.e. running this on image debain_1.img and then closing the container, starting fresh and running on image debian_2.img will result in /mnt having debian_1.img mounted inside.

Currently the only way to fix this is restarting docker.

the fix for this is to run:

losetup -d /dev/loop0

which unmounts the loopback device. This should prevent the mount from persisting. I suspect /dev/loop0 is actually running in the Mac Docker VM.
