[sf-lug] UUID seems unique for each partition

    i ran dumpe2fs /dev/hda{1,2,3,4,5} and got unique
UUIDs for partitions 1,2, and 5 and for 3 (swap) i got
"no magic number..." and for 4 (the extended partition)
i got "...too short...." And the UUID for 1,2,5 was really
different--no obvious pattern (e.g. part of the number
would be the same or some incrementation...).
    it surprises me no end that each partition has its own
UUID, as i was sure the manufacturer provided this for
each device. if i make more partitions, something is
going on (with fdisk?) that creates a new UUID, yes?

    thanks, jason, for showing how to use UUID=<value>
as a label in /etc/fstab
