Two related questions:
Is there any chance that some elements of your info_list become larger
than 4K size limit cfengine places on scalar variables?
Similarly, I wonder if the 4K size limit comes into play when a list
is interpolated into a string, as in your r1 report. I'm merely
speculating; I don't know one way or the other.
Plus, I've never tried defining a slist with a comma after the final
element. I assume that works for you, but I'll just note it for the
record.
