Just the tip of the iceberg problem here with UUID's, I've had them be
made invalid by changing the brand of sata/usb3 adapter because the
first one failed, they can and will change if you adjust anything on
that drive. I didn't lose a byte recovering from that because I was
mounting it in fstab by my fav method.
I much prefer to use the LABEL=name, with a unique name for that
partition, it seems immune to everything but a partition table erasing
full format.
Hi dep,

And the UUIDs will give you a hard time when you duplicate drives and
boot with two identical UUIDs. e.g.:
dd if=/sda of=/dev/sdb
Remove /dev/sda - it's the old one, replace it by /dev/sdb. Put the
old drive on the shelfe for backup.
Some time later you need data from the old drive (will never happen,
for sure) and connect it to your system with a sata-usb-adapter or
plug it into a free sata port of your mainboard. Reboot or mount the
drive ... fun guaranteed :)
That said, uuids are kind of coll, but they get in my way all the
time, just like the "new" aka GNOMEish naming schemes for e.g. eth0.

the time it gets here I hope I'll have cooked
up a good fstab for
it -- the existing drives will have to move down by one letter, so
my sda4 will become sdb4 b4 I can use it. And so on.
When you're about adjusting the fstab: don't use the old
driveletters anymore, a pita sometimes, take partition-UUID's, they
stay the same whatever you shuffle drives around. > Regards.
