-L looks useful too. Although I like a filesystem independant solution.

ext2fs havs volume labels. And finding somewhere in the partition table or on a reserved sector on the disk would be a better place. All you'd need to do is fiddle fdisk a bit so it doesn't use the last (or second, or whatever) sector on the disk. (hey most disks waste a few sectors anyway so that partitions can start and end on cylinder boundaries) You stick a magic marker at the front of that sector and if the kernel disk probe finds that sector, it reads names out of there and creates devices based on that. fstab says where to mount them. And it's compatible with DOS and Windows as long as you do the fdisk from Linux, or persuade Win to leave some space free.
