I ran this command:
./tools/launch $BOOTIMG --publish $ROOTTGZ -- curtin -v -v -v install --set 'json:network={"version":1}' "PUBURL/${ROOTTGZ##*/}"
Whether or not this should work (you need to add "config=[]" to the network field to do what I wanted) the failure mode was super confusing:

This is because install_missing_packages in curthooks.py makes all sorts of assumptions about what config contains (there are other ways to break it too!). Shouldn't the config be validated against a schema (in some sense) fairly early on and rejected if it doesn't meet expectations?
