Coerce Grub2 to display partition LABEL in displayed menu

[Richard Owlett]

How do I coerce Grub2 to display partition LABEL in displayed menu, 
instead of device id - i.e. sda1 ... sda10.

I have one machine dedicated to experimenting. It has multiple 
(differently configured) installs of the same Linux release.

*WITHOUT* manually editing grub.cfg each time I add/remove an OS how 
force the menu to display the carefully chosen meaningful partition 
label. I don't care if grub uses UUID's internally. I want a meaningful 
menu displayed.
