Ah, that's clear now. In a deferred transition, the frontend finally stops the run (after the 
condition is given to finish). Since the client calls cm_transition(), the script gets executed on 
the client. Changing that would be a rather large rework of the code. So maybe better call a 
script which executes another script via ssh on the server.
