Yeah, but in what sense is that use of Mach a serious microkernel, if it's only got one server: BSD? I've never understood the point of that sort of use. It makes sense for a QNX or GNU/Hurd or minix or Amoeba style of architecture, but how does Mach help Apple, instead of using the bottom half of BSD as well as the top half? Not that there can't be a good reason. There probably is. I just haven't heard it. -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
