There is another method of disk naming, I think it gained popularity
between /dev/sda and UUID, that was something like LABEL=swap or
LABEL=root. I haven't used it in years so don't remember the details.
As for building on bare metal, as it stands, during installation, the
RedHat way is you make, for example, a /boot, / and swap, then make the
same partitions on drive 2 (for a RAID-1). You then create 3 RAID devices,
one for each partition. Then, when a drive fails, you have three devices
to worry about. In contrast, as mentioned on the CentOS wiki, one can just
do a normal install, then mirror the drive with just one RAID device. I'm
guessing that is what was meant.
