A system ought to object if it sees the same UUID (or rather non-UUID)
on two disks at the same time. Probably not letting you mount anything
from the non-boot media from the startup scripts.
The 'fun' starts when you do a physical disk clone - not that uncommon.
All the RPI images are likely to be physical clones.
Using the disk 'serial number' (from ATA identify) probably isn't a
good idea - I've see multiple CF cards with the same number, and I've
no reason to believe anything newer is any better.
