I was going to say something smart about how zfs could contribute to improved serialized compression. However, I retract that and think that when one starts with order, it is best to preserve order and not attempt to re-create order once things have devolved into utter chaos. This deduplication technology seems similar to the Microsoft adds I see on TV which advertise how their new technology saves the customer 20% of the 500% additional cost incurred by Microsoft's previous technology (which was itself a band-aid to a previous technology). Sun/Solaris should be about being smarter rather than working harder. If data devolution is a problem, it is most likely that the solution is to investigate the root causes and provide solutions which do not lead to devolution. For example, if Berkely has 30,000 students which all require a home directory with similar stuff, perhaps they can be initialized using ZFS clones so that there is little waste of space until a student modifies an existing file.
