Both methods have flaws due to circumstance. I like both methods and
usually go with labels and specify the names at boot. I like the idea of
randomizing names in default installations. I put labels as below.
cat /etc/fstab
LABEL=/80g / ext3 defaults 1 1
LABEL=/boot80g /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
LABEL=/home80g /home ext3 defaults 1 2
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
LABEL=SWAP-hdb3 swap swap defaults 0 0
/dev/hda5vol/LogVol01 swap swap defaults 0 0
