Yep, that's what I'm reading now. I've actually had it for some time, as you can tell by the publication date and the fact that it's currently out of print. But, the exam is still good and, when I pass, I'll be Linux+ certified for life.
That's the nice thing about the CompTIA certifications. They're good for life. One test, one certification. Forever. Pretty sweet. And, since I'm tired of being a one-trick Novell pony, lifetime certification looks pretty darn good.
I'll keep you all posted on my progress.
