FreeBSD 8 . . . NetBSD 8 . . . OpenBSD 8 Page 8 of the fourth edition mentions various BSD Unix systems in the section "Friction Between UNIX and Linux". Page 12's mention of BSD Unix in the fourth edition appears to correspond to page 3's un-indexed mention of FreeBSD in the third edition (specifically FreeBSD 3.4), in reference to the example Unix OSes they chose to use when discussing various OSes, though FreeBSD is not mentioned specifically in the fourth edition on that page and BSD Unix is largely referred to in a historical context. This appears to be a legitimate case of BSD Unix being phased out of part of the text as a relevant OS, but it is not a section that actually says anything of specific technical value. Pages 1268-1273 in the fourth edition correspond to the bulk of the section "A Brief History of System Administration" in the back of the book. The third edition's equivalent is the end of page 2 and a little over half of page 3, "The Sordid History of UNIX". The fourth edition's index mentions "jail, chroot" which, when investigated in the text, has nothing at all to do with FreeBSD jails; it's just about chroot. The third edition also contains information about chroot, but does not mention it under the J section of the index. It looks to me like the fourth edition probably presents quite a bit more historical information particular to BSD Unix systems than the third edition, judging by the index. In the table of contents, I see that the third edition has a section set aside for BSD printing, despite lack of mention in the index. It looks like the table of contents section for "BSD and AIX printing" in the fourth edition (the first edition to include coverage of AIX, apparently) goes into a fair bit more detail about what's in the equivalent section. It looks to me, at a glance, like the fourth edition probably kept all of the BSD Unix related stuff from the third, probably updated slightly but not expanded outside of historical information. While a failure to expand technical information on BSD Unix systems would result in a reduction of the percentage of the book that covers BSD Unix technical matters, given the growth in size between third and fourth editions, the quantity of technical information about BSD Unix systems does not appear to have shrunk at all, from what I've seen. Of course, I might easily have overlooked something. Is there something else I should try to find in the index or table of contents that would be in the third edition but not the fourth? Can you give me some examples of the sorts of things you'd expect to find in the table of contents that is lacking in the fourth edition but present in the third? -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ]
