Hello Everyone,
I have been working on reworking the upstream spec file to work with centos. I've been keeping track of my progress on my github page [1] and I welcome pull requests if you find a problem.
I have pulled out all of the code related to the building the kmod, as I think that should at least be rewritten from scratch and quite possibly should live in it's own spec file. I did turn off the transarch paths configure option, which will break external scripts that expect the legacy paths. Turning off the transarch paths also meant I had to put moved files back into subpackages and I might have misplaced some files and not noticed.
Finally, I've gotten the userspace packages building in koji [2] with minimal testing. Use at your own risk; they might kick kittens. Note that these are only userspace packages. You'll need the kmod from some other source to make the client work.
