[ale] How to see and minipulate partition labels

[mhirsch at nubridges.com (Michael D. Hirsch)]

I've noticed that recent distributions (RH 7.3, for instance) don't 
mount partitions in /etc/fstab acconding to the device, but by label.  
So, for instance, I have a line like:
LABEL=/var              /var                    ext3    defaults     1 2
in my /etc/fstab.

I can't figure out how to create labels, or even how to read them.  Is 
it a secret thing in fdisk or parted?  Which FM should I R?

Thanks,

Michael
