Amiga & AROS Saturday November 8, I received an email from someone, inquiring if I would be interested in "doing a first interview/introduction into a new operating system". We get these emails and news submissions all the time, and most of the time, "new operating system" means Ubuntu-with-a-black-theme, so we don't bother. I figured this time things wouldn't be different, but after a bit of digging around, there's a little more to it this time.

Now is-it possible to build a new OS with the Linux or FreeBSD kernel underneath?


MacOSX is actually such thing, in lower levels, it runs a forked FreeBSD (Darwin).

OSX runs on a Mach kernel, not a FreeBSD kernel.

OSX runs on a Mach kernel, not a FreeBSD kernel.

"Darwin is built around XNU, a hybrid kernel that combines the Mach 3 microkernel, various elements of BSD (including the process model, network stack, and virtual file system),[2] and an object-oriented device driver API called I/O Kit."

So, it does have BSD elements in it and it is not a pure Mach 3 microkernel either. Also, the userland consists of code taken from NEXTSTEP, FreeBSD and a several others.
