1. UUIDs are system generated and can be easily assigned during 
installation, whereas labels are human assigned custom values. Imagine 
what would happen if two disks had the same label and the installer 
placed them in /etc/fstab? Even if you make the installer show an error,
it'd be cumbersome to change it midway, during installation. So, while 
installing I'd prefer UUID. Later on, while manually assigning mount 
points to partition, I can use Labels, if need be. What if they had no 
label (or a generic one) at all? (Some people are lazy enough to not 
assign labels and let the computer do the job for them.)
2. A person is much likely to change the Label of a disk than changing 
the UUID. (Let's say you named your disk PETRA. If you buy another one, 
you might want to rename it as PETRA-1 and call the new one PETRA-2.)
3. Changing Label is slightly easier than changing UUID.
