BSD and Darwin derivatives DragonFly 1.8.0 has been released. The biggest kernel change in this release is the addition of virtual kernel support and a virtual kernel build target. The biggest user-visible changes include updates to third party applications included in the base system, a major rewrite of NULLFS which removes all directory recursion restrictions from mount_null and removes nearly all the kernel resource overhead when using such mounts, and a multi-ip feature for jails.

"The FOSS BSDs have a great heritage and history, but its getting a little long in the tooth. It would be great if these very talented developers could learn to set aside their egos and work on a more viable project (i.e. Linux), but I understand that they have great pride in their work and great faith in their ideas. As long as some people find it useful, I support their efforts 100%. But they're not taking commercial marketshare, and they probably never will."

When people bring commercual marketshare up in a linux thread they are told that it doesnt matter... Why does it matter in a bsd thread then?

Personnally i don't see linux as a more viable project... only more hyped.

I didn't mean to flamebait. If you want to talk about technical merit, I'm more than willing to do so. My point was that DF is no more scalable or sophisticated than Linux.

That's not hype, that's the truth. Linux has been proven to scale well to the biggest machines currently available (2048 CPUs I believe). I don't think DF can make that claim.

Like I said (and you quoted), I support any free software project as long as anyone finds it useful. The guy I was replying to claimed DF could take on big UNIX, and that's a ridiculous assertion.

I did'nt see your post as a flaimbait. Nor do i hope i responded in a way that lead you belive i did.

"That's not hype, that's the truth. Linux has been proven to scale well to the biggest machines currently available (2048 CPUs I believe). I don't think DF can make that claim. "

What you and i think is irrelevant. What actually works out there is what matter. And i wasnt talking about your claim about linux scalling well when i was talking about hype. I was talking about linux in generel. You might just have found an area where it actually does that fanboys and the like says it can.

"Like I said (and you quoted), I support any free software project as long as anyone finds it useful. The guy I was replying to claimed DF could take on big UNIX, and that's a ridiculous assertion."

Thats a harsh remark. Unless you have seen some tests that can prove you right.

It is obvious by your comments, you are talking through utter ignorance. DF, if successful, will be revolutionary. You say Linux scales up to 2048 CPUs, but on what kind of system? Is this the same kernel I get on RHEL. Can I use this same kernel on a 4 CPU systemm? What Linux version allows you to mix any amount of computers with whatever amount of cpus and treats them all as one logical computer while being able to scale linearly? The answer is none.

DragonFly is the only serious OS doing this type of research. It will be able to accomplish this type of scalability because rather than rely on locking, spinning, threading processes to infinity, it will assign processes to cpus and then allow the processes to communicate to each other through messages. The two models of scalability are sufficiently contradictory that it becomes relatively impossible to implement both. I can assure you that if there is someone working on it, they stole the idea from Dragonfly and will either a) be forced to fork the Linux kernel (hence it is no longer Linux) or b) spend so much time trying to synchronize their kernel with the production Linux kernel that they will not ever get anywhere.
