I was asked to file this bug to track inclusion of iprutils into the comps group so that it is present for ppc64. Even though we only want this added for ppc64, we are following the example of yaboot, which is only for ppc64 too (and is on the comps list). iprutils is a package that handles the I/O adapters on ppc64 IBM Hardware. It includes a daemon that, among other things, can drastically improve IO performance during install. the package is already present in Fedora and is well-behaved.
*shrug* Note: if you have packager priveleges, you can add this to the comps file (it's in git on fedorahosted.)

Actually, it's already there. See the core group.
