It uses parts of FreeBSD's userland and libraries, and some portions of the kernel originated in FreeBSD (for example their /dev/random is a port of the FreeBSD /dev/random), but their kernel is derived from NextStep, and has significant differences from FreeBSD's kernel in many ways. -garrett -- garrett rooney Unix was not designed to stop you from rooneg@electricjellyfish.net doing stupid things, because that would http://electricjellyfish.net/ stop you from doing clever things.
