Kevin,  

If you are unaware of the gains, ask for it.  Image based upgrades are very common in cloud environments I work with.   It is used as alternative to configuration management in some places and it is incredibly useful to be able to deal with a consistent standard image and only provides deltas for upgrades.  Chrome OS does that for example and it is used in some of the most popular laptops in Amazon with millions of consumers.
