That's why I asked for a configuration which only uses suicide in a

configuration and I could not find anything suitable (some people asking 
for the same thing though) so I suspect it's not possible (yet?).

Read below please.

This point is way more obvious and I am going to go this way instead of 
the suicide stonith. Sort of a friday morning blindness on my side ...
