Actually. I'm using the Logical Volume Manager to set up space for Guest OSs and to set up the volumes on the RAID array.
Wouldn't SELinux have a mitigating effect on logging in as root? (Though you have convinced me that I should just set up a user account and su/sudo as needed.)
CentOS uses Gparted during the graphical install (I think) and it was very handy. I put my OS in its own Volume Group and Logical volume. I like that I can add to it if I need more space. I don't have to try to guess how much space I'm going to need in two years. For a first time user/admin that is great.
