It wasn't copied and it wasn't a bug, but my misunderstanding.

Attributes are not directly copied since there is no one-to-one mapping
between jobs and coaster blocks. So theoretically some "merge" operation
needs to exist.

I added "ppn" as one of the attributes that is copied from the first
job, so the scenario I mentioned should now work.

This is cog r2927/trunk.
