I've not been able to determine this either, but as it requires kernel
re-configuration, I usually just know. In my scripts, I make sure and
fail if the call to create a vnet jail fails:
sh -c 'TEST=$(sudo jail -c vnet name=test host.hostname=test path=/) ;
if [ $? = "1" ]; then echo "VIMAGE NOT AVAILABLE" ; exit 1 ; fi'
...or something like that.
There may be a better way, or perhaps there should be.
