Or will the build process create 3 srpm files one for each rpm based distro? Still learning about rpm spec files been in the .deb world for that last 8 years.

From what I can see of the format of the engine repo there shouldn't be any issue in just having debian packaging files in the repo and just pulling them out for the build process. > 3. possible missing options to create srpm and src tarball > > > ovirt-node: > > only really supported on fedora right now.

EL6 builds would be nice not sure how many changes would be needed. Judging by the fact the current EL6 builds don't build nodes it is more then trivial.
