[9fans] What is Plan9 exactly?

I've been looking at plan9 on the internet and to say the truth, I'm 
mystified. What is it exactly? Is it meant to totally be better than 
Unix or any Unix-like system? How so? What kind of kernel does it use?

Yeah, I'm mystified myself. Is this a troll or a serious enquiry? Trousers
rolled.

I'm serious. I'm a Unix fan, I use BSD, Minix, Linux, and any unix-like OS I can get my hands on. Sadly, except, System V or HP-UX, or any UNIX. I read about Plan9 online, and it sounds like a great project. Though I do think that if this operating system if made to be better than Unix in every single way, it has to have a better kernel, which is something I am very interested about. What kind of kernel does it use? Why would anyone use it?

All of this is on the wiki. I'd take some time to sit down and explore for
yourself.

I just did, though I cannot find anything about the kernel architecture

Fortunately, there is a book about it. http://lsub.org/who/nemo/9.pdf which
might have been updated to 4th Edtion,
but the overall structure is similar, although with many improvements.

Just another step on the path to the one true operating system, OS X with Golang.

Why?

P.S. The kernel is monolithic. Although, IIRC, there were attempts to make
it a hybrid.

this is far from the full story.  because of the mount driver, many things
may be in the kernel or userland according to what makes sense.  for
example, the ip stack has moved back and forth several times.  the usb
interface implementations are in user space.  etc.  partfs(8) (sic, should
be in section 4) and sdloop(3) in 9atom are both loopback drivers that
appear to be served through sd(3), but partfs is in userspace and sdloop
is in the kernel.

likewise, resources can be imported from other machines' kernels or
userspace in the same way.  for example, i can import a gateway's ip stack
and use it directly as if it were local.

thus, while the kernel is fairly traditional, the capabilities are not.

They should be, but tradition is slow to catch on.
