Oh, man...
So, I figured I'd give Oracle's Linux a try in VirtualBox - you know, Oracle's VirtualBox...
I'm an idiot. See, I thought it'd actually be well integrated and polished. I'd use the latest VB with the latest Oracle Linux. I figured they'd go together well!
Nope... The cursor doesn't line up - meaning my mouse cursor is a good 4" away from where the virtual cursor is.
I figured that I'd fix the resolution issues, so I loaded the VBox tools. Oracle's Linux was kind enough to open and run it automatically - all I had to do was enter my password. Optimistic was I when I entered my password...
Nope. The VirtualBox addons will not work with Oracle Linux.
Yup, you got it. Oracle's Linux doesn't even properly work in Oracle's VirtualBox. There was nothing good about it. In fact, it was entirely awful.
I'm not sure why I'd expected otherwise. I should know better.
Anyhow, I think it's safe to scratch Oracle off the list of possible CentOS replacements. It was so bad that I can't even recommend testing it out in in a VM. It was that bad an experience.
