"I believe that one cannot attain Linux guru status without
understanding its kernel and other innards. Lucky for me, then,
Linux Internals offers an eight-fold path toward Linux
enlightenment in the form of eight chapters that cover the kernel,
system calls, signals, interrupts, processes, virtual memory,
scheduler and file systems."
"But beware eager apprentices; the Linux Internals path should
be tread only after one possesses a working knowledge of operating
system theory and the C programming language. For newbies this book
is not. Difficult to categorize, Linux Internals is more of a
reference work than anything. The dense content and delivery fall
just shy of textbook classification. Yet, unlike reference tomes, I
was able to read it cover to cover like fiction. Each topic is
covered in depth, some more than others, with references to other
operating systems, mostly Solaris, made for comparison."
"The material covered in Linux Internals is required reading
for any aspiring Linux kernel hacker, high performance junkie and
guru wannabe. I can recommend this text to Linux guru candidates
because Moshe Bar has crafted an informative book that strikes a
keen balance between an operating system text and a programming
manual. With the inclusion of several different Linux kernel
versions leading up to and including 2.3.99 -pre5 on CD-ROM, as
well as a few journaling file system and volume manager goodies,
the book also encourages one to tinker."
