We don't generally provide downgrade for Solaris at all; generally the current packages are not designed to go backwards in time, as it's not a requirement for the product, thus the scripts included in most packages will in many cases have fatal flaws if presented with an environment that breaks this basic assumption. It's possible that at some point this could be done, but it's a much bigger problem than Jerry's proposal. Dave
