Good catch! That was indeed the problem. Thanks a lot! :)

Definitely.

The other question is if there is a better mechanism to let the user 
know what exactly he has to update in his local configs. I see that 
there is a warning that the local config is out of date, but the local 
configs and the default configs may look quite different, and therefore 
a user might not be able to find out what he has to actually change to 
make it work.

Also, I wonder if we can somehow define dependencies between resources 
and realms (e.g. the add-realm resource requires the 
from-scratch-realm-template realm).
