Oh, ok. Then we'll just have to do all of them.

Ok. Yes, it's certainly a safer path.

Ok. See below as well.

Yes. There are two different ways. These "small utility processes" get
only some of the vars, and they get it on the commandline instead of
through a parameter file. Only the full-blown backends get all the
parameters, through the parameter file.

Claudio has a TODO item on rationalising these exec-backend startup
issues. I think the final fix will have to be either includedi n that or
bolted on after that. I think we should probably move all the backend
startups into using the same method, probably the file, but still
discussing that with Claudio.
