Amazon.com just posted my four star review of Embedded FreeBSD Cookbook. From the review:
"When I skimmed 'Embedded FreeBSD Cookbook' (EFC) in the bookstore, I was impressed by the amount of general FreeBSD information it contained. Now that I've bought and read it, I'm glad this book caught my eye. Although EFC is somewhat dated by its use of FreeBSD 4.4 (released Sep 01), I learned more about about FreeBSD internals. I also gained insights into what is needed to create an embedded appliance from the ground up."
On a related note, I still need to check out the papers from EuroBSDCon 2004.
