Yes, they can be changed. Use the -U option in either mkfs.ext3 to set a particular UUID while making the fs, or in tune2fs to overwrite an existing UUID with one that is more to your liking. If you maintain a small database of UUID values for your disks, you might be able to automate. Or look into establishing for yourself a policy of using LABEL on all your disk partitions. The install program seems to automatically rewrite UUIDs if you ask it to erase a partition. IMHO, the method for handling disk naming is still a work in progress. In the meantime, my particular kluge involves using labels. They are shorter to type and easier to remember. My understanding is that a UUID is just a string of hex characters of the defined length and with embedded hyphens at the defined internal locations. Generate a half a dozen and they are almost certainly all different, even if you are using a very bad random number generator. That they are all different is what makes them useful. The problem is highly over intellectualized.
