PPC64(le), s390(x) and aarch64 are all Fedora secondary architectures.  
Each one has its own Koji environment, seperate from the primary env in 
the Fedora infrastructure.  Koji-shadow works by pulling build 
information down via the Koji hub web server, not using a shared NFS 
mount.  As each shadow koji manages its own build yum repos, access to 
the primary koji's NFS mount isn't needed.  My recollection is that the 
original Fedora ARM Koji setup (when armv7hl was a secondary arch) was 
hosted at Seneca in Toronto.

So, if you want to use the Fedora model, all primary arch builders need 
access to a common NFS mount.  Any secondary arches don't.
