If you invent a new file for a new uuid like this then it's highly unlikely people will reset it when building such images, and hence your counting will count all such instances as one, which you probably don't want. Hence, any such uuid should be keyed off /etc/machine-id, as that file exists for purposes like this, and the chance that it is reset during image building is higher, and doesn't require people to reset uuids all over the place. hence my recommendation to derive the any uuid for purposes like this from /etc/machine-id, by using a HMAC of some kind (see other mail).
