For the first time it's possible to choose which kernel you want to use for the popular Linux distro Debian, either the Linux kernel, or the¬† FreeBSD kernel. This FreeBSD kernel support is added to both the "unstable & experimental" editions.
Debian distinguishes itself as cutting-edge by adopting FreeBSD & thereby sets a new example for an Operating System: a platform supporting 2 very different kernel technologies, with other aspects of the software remaining largely unchanged.¬†¬†
Here's the anouncement from the developpers:
We just added two new architectures to the Debian archive. Everybody please welcome
¬† kfreebsd-i386 AKA GNU/kFreeBSD i386
¬† kfreebsd-amd64 AKA GNU/kFreeBSD amd64
Note that this enables porter NMUs for those two. In case you have a bug with a patch waiting for your package that has to do with one of them, please either fix it soon or expect a porter NMU to be done soon.
The two new architectures (well, better named OS i think, as they use a different kernel) are available in unstable and experimental. We do start out empty, importing only what is needed to get a build running. For this reason you will not be able to directly use it immediately. Please wait until they catched up, which I expect to happen soon.
