Ah OK, in that case switch host_name and dependent_host_name and
service_description and dependent_service_description around.

Is that not what you need? You asked in your original question "how to
specify than A depends on (B or C) ?"
The documentation says "You can create several dependencies for a given
service, but you must add a separate service dependency definition for
each dependency you create" which I would read as you'd need to create 2
separate servicedependency entries, one for the dependency on
host/service B and one for the dependency on host/service C to get this
effect, again I'm not 100% sure.
