 def kernelVersionList(self, rootPath = "/"):
        versions = []

        # FIXME: we should understand more types of kernel versions and not
        # be tied to rpm...
        import rpm
        ts = rpm.TransactionSet(rootPath)


Would not defining rootPath to be "/" be the same as leaving
TransactionSet() undefined, as the default is to use "/" anyway?
This fails for me, the rootPath needs to be "/mnt/sysimage" as that is
where the install target is mounted at that point in the install.
