No, I'm not that crazy . Debian per definition is not a complete
OS. Debian rather means and provides the management tools and
programs/software necessary to administer and use a system i.e.
it's not a full OS, but one part of it. To make up a full OS, a
kernel is necessary, and Debian primarily uses the Linux kernel,
hence why the most common flavour of Debian is indeed Debian
GNU/Linux. But there are also some non-Linux ports of Debian,
i.e. ports of the tools and utilities that it consists of and
uses to manage the system, to other kernels, FreeBSD's being one
of them. Other non-Linux Debian ports use the Hurd, NetBSD or
OpenSolaris kernel. From Debian GNU/kFreeBSD's page: Debian
GNU/kFreeBSD is a port that consists of GNU userland using the
GNU C library on top of FreeBSD's kernel, coupled with the
regular Debian package set. (GNU userland = important Unix
commands and libraries to perform basic operations.) An analogy
would be if I decide to build my own car, I can build the
chassis , the steering wheel,
