Too late now, but git bisect and running the test suite seems to be
broken starting with this patch as I started getting "FAIL:
qemublocktest" here running a bisect chasing something else.

As I found out "later" I didn't have jansson-devel dnf installed either,
so that may have affected my results. Who knows at this point.

The failure goes away with patch 13, but that introduced other issues
for me. I'll respond there with what I found.
