But I still use carefully managed labels instead of hard to remember UUIDs and it you lose it, its a pain to recover. It's easier for me to see: f11-boot, f11-root, f-App1, u9-boot, u9-root, ..., w2kPro, w2kSvr, VistaH, XpPro, and so on. I have many different OSes dispersed over many HDs. As for grub itself, I use a grub "tree-structure" and the primary boot grub so happens to be based on F8-grub and on the drive's 1st partition, followed with whatever grubs each OS supports and each in it's own boot/root partitions per drive and usually all in the extended partition. All of my OS SATA drives uses the maximum of 15 partitions, so that the tables are always preserved, I learned this the hard way. All in all, it works very well. The point is, labels and/or UUID are not a requirement, but a perhaps convention? This could change though, but I hope not.
