Fedora 12 has IMA enabled in its kernel by default. OpenAFS can't  
currently co-exist with IMA, because IMA fundamentally breaks the core  
interface that OpenAFS uses it access its disk cache. There is ongoing  
work to fix this problem in the kernel.

The alternative is that we modify the OpenAFS cache manager to use an  
alternative, but significantly slower, mechanism for opening files in  
the cache. This has been done on an experimental basis, but we'd  
rather not end up having to support two different mechanisms for doing  
this, if the IMA problem ends up being a short lived blip in kernel
