Design & Implementation 4.4 BSD vs FreeBSD
Hello all. Having only used FreeBSD, would I be better off getting the more up to date Design and Implementation of the 4.4 BSD Operating System or the more out of date Design and Implementation of the FreeBSD Operating System? I'm making an assumption that knowing 4.4 BSD will also give me a more versatile understanding of the BSD OS. Would I be wrong?

There really isn't a "BSD OS" anymore, today's BSD derivatives are based upon the indeed 4.4BSD & 386BSD releases, but they have each diverged considerably.
They do still share code, how much is unclear, but plenty of design changes have been made that render that book obsolete.. with OpenBSD for example, the developers consider the kernel source itself the definitive source of up-to-date documentation. Reading the books can't hurt, so I'm not going to recommend that you don't. |

http://www.amazon.com/Design-Impleme...0959756&sr=8-1 ...sports a copyright date of 2010. This is misleading given that this appears to the 4.4BSD hardcover book simply being re-released in paperback. This book is not being advertised as a second edition, so I don't suspect there is any new/additional material. Quote:
Those who are fans of OpenBSD and/or NetBSD would probably get more out of the older 4.4BSD book as compared to the FreeBSD-specific version. OpenBSD-types might also find the following thread useful for book recommendations: http://marc.info/?t=109899112500001&r=1&w=2 ...although the thread is six years old. |

I'm not sure how much code is shared between the projects, but I have seen enough NetBSD copyrights in the FreeBSD userland to learn how to smile at it .

Both wired & wireless network drivers frequently start in one project before getting ported to the others. The developers (at least in OpenBSD...) frequently know what has been checked into family member source repositories. |

Thanks everyone. And thanks for clearing that up ocicat. For some reason I was thinking it was a new edition. I'll get the FreeBSD one.

the real question is how often do they get meaningful patches back from the porters, after the port.

TerryP, you are taking discussion in a different direction than the OP. If you wish to continue discussion, start a new thread in an appropriate subforum..

My apologies m3t4tr0n
