Does this differ significantly from Sobell's other distro-specific admin books? Specifically, I had (probably still have somewhere) one of the "Practical Guide to Ubuntu Linux" editions. While it was OK for what it was, I still found myself digging up information on the net more often than referring to the book.
I guess I'm wondering if this is essentially the same book, but with information presented in a distribution neutral manner instead of targeted to Ubuntu? Or does this this book really present fundamentally different information (or the same information in a fundamentally different way)? Basically, if I have the Ubuntu book, is there any reason I should even take a look at this book?
