Re: [BLUG] Amarok

Ummm, well, UUIDs are funny things.

For one thing, taking the image of a partition and restoring that
partition on any other media will have the effect of creating a
filesystem with the same UUID.

This is GREAT if you're taking an Ubuntu image from one machine and
moving it to another, as your filesystems will have the same UUID and
thus the mounting will work right.

HOWEVER, just as I use images to save time installing a large number
of machines; it seems that some external hard drive manufacturers have
taken to using images to save time slapping the read me files onto all
their hard drives.

I learned this when my computer wouldn't mount both my brand new 1TB
USB drive and the one my father bought at the same time, same place;
it thought of them as the same hard drive, since the UUIDs were
identical.

Just a tangential heads up.
