Here’s two slightly tangential things that involve DragonFly: The first is a thread about large (64-bit) file support in Apache, and how it is treated as a special case because of poor planning under Linux - it’s not a problem in BSD. This led to an excellent quote from an excellent book, “The Cuckoo’s Egg“, by Clifford Stoll:

“We’re watching someone who’s never used Berkeley Unix.” He sucked in his breath and whispered, “A heathen.”

Also, “_why” posted a question about checkpointing to the users@ list, for an issue that Matthew Dillon later fixed. I recall that this _why is the same fellow who wrote “Why’s (Poignant) Guide to Ruby“, a programming book that is unlike any other.
