I saw a book at the book store today that looked very interesting, and
would like to know if anyone had any advice on it (before I spend
$46.50 ;-).  The name of the book was "The Design of the Unix
Operating System", by Maurice J. Bach.

It had a lot of details of kernel internals and how things go
together.  Unfortunately, it looked a little dated, and looked like it
was based mainly on SysV (specifically SVR2 and SVR3), with references
to "BSD" (I assume 4.2 or early 4.3?).  It makes no references to
POSIX that I could find in my quick scan through.

I already have the "daemon book", which, of course, is excellent.  But
it doesn't get real in-depth in all areas, so this other book looked
like an interesting supplement.  On the other hand, I don't want to
pay big bucks for a book that's out of date and doesn't apply at all
to the operating system I'm (ab)using (NetBSD-current).

So, opinions on this book's applicability to NetBSD-current?  Also,
opinions on any other "internals" books that might be of value?  I'm
mainly interested in what the core team and other professional
internals programmers consider vital texts.  Thanks for your input!
