I would say leave the default at 0 as it leaves no doubt that you are 
performing without a net. A setting of '1' implies you are covered and 
for a fast moving cluster or slow moving one with sufficient downtime 
that would not be the case. Better to let the end user know this is not 
a simple problem and some thought needs to go into configuration.
