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
