Aside from the general "RTFS", there are probably two (or three) good places to look: "The Design and Implementation of the FreeBSD Operating System" by McKusick and Neville-Neil, or its predecessor which may be much more affordable, "The Design and Implementation of the 4.4 BSD Operating System" by McKusick, Bostic, Karels, and Quarterman. Chapter 2 of the latter is available at http://www.freebsd.org/doc/en_US.ISO8859-1/books/design-44bsd/book.html . It will give you some hints, but probably not as much detail as you want. And, of course, reading the archived threads on the topic, already referenced by others, will provide a quick education in the issues involved. I think that would be the best place to start. - Bob _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
