Re: Ubuntu as RHCE
I'll just save you a little Googling. CentOS is literally the source code of RHEL, with some new art, a couple of different packages by default, and a different name. Perfectly legal. Everything you can do on RHEL you can do on CentOS, as far as I know.
However, that's no reason not to use Ubuntu on your desktop when you're not learning Red Hat
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
