using labels in grub2. How?

view full story

http://www.linuxquestions.org – I want to generate a grub.conf that will search for my /dev/sda1 based on the filesystem label, not the UUID. I did change /etc/default/grub to so that GRUB_DISABLE_LINUX_UUID="true" and I regenerated grub.cfg. But I want to go one step further and change the search statements. I notice they still reference the old UUID. I also know grub2 can search by label. Can anyone tell me how to do this? Thanks. EDIT: I could use some help understanding this page: (HowTos)
