b. Also, who generates these UUID - is it a disk property (like, ROM signature or stuff?), or this is some udev magic?
IMHO, this is fixed for every device during manufacturing.
I believe the UUID is created per partition/file system and are created when creating the file system for a partition. If anyone even had their drive changed from /dev/hda to /dev/sda due to linux changing how they labeled ide drives they will know why people use UUID instead of the device name . Also, it is not guaranteed that they drives will always come up in the same order between kernel releases(This is my personal opinion). -- John
