Just installed and got to running my first experience into the Linux realm with Mandrake 10 OE. I am looking to purchase a book that can help me learn about how Linux as a whole, or more specifically, how Mandrake runs as an operating system. Although I have a considerable (IMO) amount of BASIC computer knowledge, I am looking to "learn from scrath". Could anybody recommend a book or related publication that could get me at least a good start from the ground. I am truly looking to start from the ground, as I dont want to overlook anything simple.

Here's a good starting resource:

This is good also:
