The way mock compiles RPMs, it would be built on each builder separately. The possibility exists that something very minor can (and sometimes does) happen to make things not exact. I will analyze these an tell you the difference in an upcoming e-mail. We have changed our policy and now we will use the same noarch file, from one of the arches, on both if it exist in the arches. That policy did indeed cause a change in the MD5SUM as they were different before. Again, I'll post in another e-mail what is different between the two, but this is as expected. It should not happen any more moving forward though, as we will only ever release ONE noarch file in future, regardless of it they built slightly differently from the builders. Thanks, Johnny Hughes
