That's good news.

Just to get it right: 'make run/demo' now works on Linux and NOVA as
expected, right?

I've to admit that it's expected that the hello tutorial works on
Linux but not on NOVA. The first-application tutorial on Genode leaves
aside several aspects, which are important for other kernel, for
simplicity reasons. In this case the service for accessing x86 I/O
ports (needed by the timer) is not configured properly. You may add

  <service name="IO_PORT"> <parent/> </service>

to the top of your config file. For further information about
confiuring the init process please have a look at
