I only found the list after looking for a resolution to my problem. server node:/etc/rpm/platform: i686-redhat-linux compute node image:/etc/rpm/platform: x86_64-redhat-linux as indicated in my initial post. This is a clustered system. I have a x86 server and x86_64 compute nodes. I am trying to install the x86_64 RPM's into a mounted disk image on the x86 server using the --installroot flag.
