daemon book: n. "The Design and Implementation of the 4.3BSD
UNIX Operating System", by Samuel J. Leffler, Marshall Kirk
McKusick, Michael J. Karels, and John S. Quarterman (Addison-Wesley
Publishers, 1989, ISBN 0-201-06196-1); or "The Design and
Implementation of the 4.4 BSD Operating System" by Marshall Kirk
McKusick, Keith Bostic, Michael J. Karels and John S. Quarterman
(Addison-Wesley Longman, 1996, SBN 0-201-54979-4) Either of the
standard reference books on the internals of BSD Unix. So called
because the covers have a picture depicting a little devil (a visual
play on daemon) in sneakers, holding a pitchfork (referring to one
of the characteristic features of Unix, the `fork(2)' system call).
Also known as the Devil Book.
