I've been getting requests from users concerning the best way to roll out new service packs and hot fixes to their SQL Server computers. A perenial question that always seems to come up is "Why doesn't Microsoft slipstream (that is, add the hot fixes and service packs directly into the product) updates for SQL Server?"
This is an important philosophic question about what is the best way to support a production software product. It all comes down to mindset and how you prioritize various issues. I can't pretend to speak for Microsoft, but you can get some great insight into these issues by reading Euan Garden's, a person I emminently respect, blog posts on this topic at http://blogs.msdn.com/euanga/archive/2006/04/27/584637.aspx.
Let me, and more importantly Euan, know what you think.
