Okay. Thanks for informing me. It will be great when Genode reaches that point.

The topic has been discussed before:
http://sourceforge.net/p/genode/mailman/message/30417127/
Binary compatibility across different kernels is not entirely
unreasonable. We are actually working in this direction to make the
future distribution of binary packages manageable. Instead of providing
packages for each combination of kernel and architecture, we would need
to provide packages per architecture only.
Even though we are still not near to reach this goal yet, we are taking
steps towards it. E.g., the development of our new dynamic linker (that
will be part of the next release) was motivated by that.
There are two non-trivial remaining points that still must be addressed:
* The kernel-specific headers in the respective 'base-<kernel>/include/'
directories have to be generalized. This is not easy because
some of them define kernel-specific types (e.g., how a capability
is represented) that are used by the generic headers in
'base/include'.
* The build system must be enhanced to support the build of kernel-
specific and kernel-agnostic parts in different locations, yet
integrate both into one view at the system-integration step. This
is an architectural change of the build system. The challenge here is
to preserve the robustness and convenience of the current work flow.
Cheers
Norman
