Being new to Yocto I found this book to be a great starting point. There is a lot of information here and the authors did a nice job presenting it. I plan on getting back into embedded soon (ARM) and this book should come in real handy. I do have two rather minor points: I would have preferred more in-depth examples, and in these examples I want to see the current directory on the command line (PS1 var). I realize this may have been omitted to save space, however, it was often difficult to know what directory to be in and it would have prevented some of the mistakes I came across.
