“Another hallmark of Debian is that it really deserves its name
of ‘universal operating system’. There are official CD and DVD
images for various architectures: amd64, armel, i386, ia64, mips,
mipsel, powerpc, sparc, and s390. So if you have an old Mac with a
PowerPC processor lying around, you can give it a new life with
Debian, or if you want to install a full Linux distro on your NAS
with an ARM processor, chances are that Debian supports it. The
Squeeze release even has for the first time two non-Linux
architectures: kfreebsd-i386 and kfreebsd-amd64, which give you a
complete Debian system on top of a FreeBSD 8 kernel, which is nice
if you want features like the ZFS file system.”
