Suggestions on Linux Manuals

[Max Pyziur]

Greetings,

In 2002, Gerhard Mourani's Securing & Optimizing Linux: The Ultimate 
Solution was the single paper resource that met many of needs and was tied 
to my skill level.

Would anyone have recommendations on what the 2010-going-into-2011 update 
to this weighty tome be?

Thanks!
