Yes correct they are not installed in our package. In fact upstream
ships them as example and I think expects that everyone implements in
the respective distro specfic fashion. The example scripts contain,
e.g.:

# Each Distro is expected to implement this script in a distro specific
# fashion. For instance, on Distros that ship with Network Manager enabled,
# this script can be based on the Network Manager APIs for configuring the
# interface.

Ben, Bastian, Uwe, I wonder if we really should do here something or
accept the warnings from the missing installed scripts as stuff still
seems to work by users.

Opinions?
