You build one image, which creates a 'ceilometer' user with UID 1001,
and deploy that to your cloud.

You then build a new image to deploy to your cloud, and due to element
ordering (or something else), the 'cinder' user now has UID 1001. When
you switch to this image, /mnt/state/var/lib/ceilometer is now owned by
cinder.

If it (dieting) was like a real time strategy game, I'd have loaded a
save game from ten years ago.
