The problem with /dev/sd? devices is that the are named in
the order detected at boot time so they may change if you
add or remove disks or controllers.   The problem with
labels is that if you add a disk to a machine that happens
to have a duplicate label the system will be confused and
may not boot.  I prefer to use the partition names because
the behavior is more predictable when you move disks around
between different machines.
