I haven't checked RHEL5. If we can't rely on scsi_id to work the same way
across udev releases, then we could just pick a version of the code and
copy it into libvirt tree, stripping it down to only the function we
actually need. It isn't that much code and doing that's probably easier
than playing games with a tool that changes its calling conventions
