I was under the impression from past emails on the MTD list that the 
internal meta format for UBI has changed a few times over its lifetime.

Assuming this continues, I would think this would cause problems for 
bootloaders such as U-Boot whose flash partitions are not necessarily 
rewritten in the case of a product upgrade - i.e. a firmware upgrade with 
a new kernel would have a new UBI implementation and spec causing an
older bootloader to fail to operate properly with the newer image.
