1.0 out of 5 stars
Not terribly clear, 10 April 2012
Just so you know where I'm coming from, RHEL4/5 admin with 5 years experience and plenty of prior experience across other OS's, not a sysadmin God, but not too shabby, looking to fill a few blanks like selinux that just haven't come up in the working world.
Bought this to help fill in a few blanks before the exam, but unfortunately found it rather rambling and unclear, inaccurate in places, and frankly feels like it has been rushed to market without proper editing or proof reading. For example, the chapter 'The Boot Process' is not the place I'd expect to find details of ifconfig, network configuration and ntp. It frequently doesn't expand on acronyms (pretty standard practice in any technical documentation in my experience the first time you mention something), for instance 'MLS' (Multi Level Security) in relation to SELINUX is not expanded at any point, leading to frequent visits to the web to clarify points.
It lacks any insight into what is happening under the bonnet, which as an engineer I find unhelpful. How can such a clearly defined subject not have clearly defined chapters and some fundamental principles covered?
In short, it's too vague to be a reference, and too rambling to allow for study and I am now in need of something more focused.
