Ah, OK. But hasn't openSUSE been using xz in their deltarpms since 11.0
(over a year ago)? What are they doing differently so they aren't affected?
1) Maybe they don't build noarch rpms on ppc
2) They use a faster compression, that creates bigger output. At least I
remember something like this mentioned in this thread or some other
discussion.
