We do not really declare module dependencies anywhere else and it would
a nousance to move any file if many other referenced it without being
necessary. Also most higher level modules depend on most of the lower
level ones.
So removing this because it can only potentially cause weird issues.
It is now only about the system service.
Granted, it also installs the client package, but that could be
factored out later, with actual test to support such a new type of
configuration.
