The definitive source is the source code itself.

While Linux has a much larger community where some books have been written (eg. Understanding the Linux Kernel), the closest tome from the BSD perspective is The Design and Implementation of the 4.4BSD Operating System.

Note that both books cited are dated.

The reason books on this subject are dated is because both the writing & the knowledge is tedious. While there is a market for such books, publishers are not excited on books such as this because the potential markets are small.

...& given that the implementations change, books on the subject quickly lose relevancy.

How developers & aspiring developers learn about these subjects in depth is simply to study the source code itself. There really is no shortcut.
