Has anyone worked with yellow book in a unix/linux environment? If so, could you provide me with more answers around this?
Do you really think that there is only one book in the world with a yellow cover? The DOD issued the "Rainbow Series" and it has a "Yellow Book" which is "A Guide to Understanding Trusted Recovery in Trusted Systems". This is most likely what you mean. But there is also a "Yellow Book" in the CD standards. "Yellow Pages" was renamed to NIS but your question is so vague that you might mean that as well. The original Bell Labs Journal special issue Unix series have yellow covers. They are my favorite Unix books of any color.
So we can rule out IBM's "Red Books"?
