Debian with the FreeBSD kernel was the subject of a heated week-long discussion. It seems that since this idea was first conceived in February, a few people have been working on the port. The status of their work can be read about here. Basically, they are using the FreeBSD kernel and libc, and recompiling Debian packages to work on that system. Reactions varied. John Goerzen worries that a version of Debian based on a BSD copyrighted kernel would open the door to third parties taking our work and making it proprietary, and also that "we are essentially giving first aid to software that is dying (and rightfully so) because of its license". Many others disagree with him and have no problems with the BSD license. Others wonder if it wouldn't be technically better, and easier in the long run, to port glibc to FreeBSD, and allow Debian packages to be used unchanged with that kernel and library combination.
