"The Debian project made a splash on Sunday with the
announcement that two new "architectures" had been added to the
Debian FTP archive. Debian has always supported a wide range of
processors, though; these architectures are different and
noteworthy because instead of providing Debian on different
hardware, they build the OS on a completely different kernel:
FreeBSD's. So what exactly does that mean?
"The FreeBSD-based ports are sorted in with the distributions
for the various processor architectures Debian supports. So far,
only 32-bit Intel and AMD64 chips are supported, designated
kfreebsd-i386 and kfreebsd-amd64, respectively. Both are still
undergoing development, and not yet ready for installation."
