This is patched in the 'dev' branch of git://git.op5.org/nagios.git
which you will have to build from source. 'null' still has to be a
valid check-command, but with the sources in that branch you should
be able to override a service-check inherited from hostgroups.

It's not very tested, but feel free to try it out.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
