What book would you recommend as a reference for Ubuntu server administration?
I'd like to not limit this to server-edition. I'm biased toward development environments that need to strike a balance somewhere between desktop & server.
One book per answer, please – vote answers up/down as you feel appropriate. If you feel the book is biased towards/good for particular tasks, please mention them.
