My Brothers and Sisters,
Should we accept that this book is indeed a Bible? Let us use a dictionary to see what the definition of a Bible is.
The first definition is marked obsolete, and just means "a book." I think that anyone would agree that this tome is a Bible by that definition.
The second definition is the one that most know, "The Book by way of eminence...accepted as of divine authority and origin." Well, Linux has long been known for its gurus who hand out small snippets of sage advice. Sometimes that sage advice is in many books, and beginners are often told RTFM (Read The Freaking Manual). Easy enough for the guru to say, but when there are so many manuals, HOWTOs, and other pieces of information scattered about, how do you put it all together?
Therefore, a Bible is necessary. Let's hope it carries information pertinent to your own religion, or in this case, distribution. If the Bible tries to cover the information in every distribution, the reader may become lost. That is why this is a SUSE Linux Bible, and not some other brand of Linux.
Some people say that Linux and Free and Open Source (FOSS) are a religion, and that the people that support it are religious zealots. I don't think that is true, for the people I know in FOSS are multifaceted. But when it comes to programming, we believe that Linux and FOSS offer education, government, and business the most flexible, most powerful, and lowest cost solution. All you have to do is reach out and accept that fact.
