- At the moment the tests are not distro / arch specific, we might need a way

  to clearly mark a test as -only-for-c4- or -only-for-c5- etc ( specially

  when there are kickstart files involved, there are some non trivial changes

  in that area moving towards c6 )

- We also need a way to dictate if a role_<test> should be run on realiron,

  virtual machine host, virtual machine ( and maybe even the type of virt

  being used! )
