  OK, I can understand a higher potential for breakage
  due to a different codebase and/or indirection .... 

  I suppose I've been lucky to never have encountered
  any problems using  /dev/disk/by-label  in fstab
  but I've only ever run machines with at most 
  2 drives along with an optical drive .... 

  I have swapped drives between machines a few times
  for one reason or another, but don't recall
  any problems with those either after fstab adjustments.
